android动态添加复选框

时人不识凌云木，直待凌云始道高。这篇文章主要讲述android动态添加复选框相关的知识，希望能为你提供帮助。
以下是我的布局xmls。现在我们在布局中有一个有限数量（七个）的复选框（listitem.xml）。我们将它添加到线性布局中。
main.xml中

< ?xml version="1.0" encoding="utf-8"?> < RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:background="#FFFFFF" > < LinearLayout android:id="@+id/linearLayout1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_alignParentTop="true" android:layout_marginLeft="21dp" android:layout_marginTop="38dp" > < TextView android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignBottom="@+id/linearLayout1" android:layout_alignLeft="@+id/linearLayout1" android:text="TESTER : " android:textColor="#000000" /> < AutoCompleteTextView android:id="@+id/tester_name" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" android:ems="10" android:capitalize="characters" android:textColor="#000000"> < requestFocus /> < /AutoCompleteTextView> < /LinearLayout> < TextView android:id="@+id/textView2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@+id/linearLayout1" android:layout_centerHorizontal="true" android:layout_marginTop="19dp" android:text="APPS TO TEST : " android:textAppearance="?android:attr/textAppearanceLarge" android:textColor="#000000"/> < View android:id="@+id/view1" android:layout_width="wrap_content" android:layout_height="1dp" android:layout_below="@+id/textView2" android:background="#CCCCCC" android:layout_marginBottom="5dp"/> < ListView android:id="@+id/apps_list" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:layout_below="@+id/view1" android:dividerHeight="5dp"> < /ListView> < Button android:id="@+id/refreshBtn" android:layout_width="wrap_content" android:layout_height="40dp" android:layout_alignBottom="@+id/textView2" android:layout_alignParentLeft="true" android:text="Refresh" /> < /RelativeLayout>

listitem.xml

< ?xml version="1.0" encoding="utf-8"?> < LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="wrap_content" android:background="#FFFFFF" android:orientation="vertical" > < LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" > < TextView android:id="@+id/app_name" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="70" android:textAppearance="?android:attr/textAppearanceMedium" android:textColor="#000000" /> < Button android:id="@+id/launch_btn" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginTop="4dp" android:layout_weight="20" android:text="LAUNCH" /> < /LinearLayout> < RadioGroup android:id="@+id/status_group" android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="horizontal" > < RadioButton android:id="@+id/pass_btn" android:layout_width="wrap_content" android:layout_height="wrap_content" android:checked="true" android:text="PASS" android:textColor="#000000" /> < RadioButton android:id="@+id/fail_btn" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="FAIL" android:textColor="#000000" /> < /RadioGroup> < LinearLayout android:id="@+id/failure_layout" android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical" > < TextView android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:focusable="false" android:focusableInTouchMode="false" android:gravity="center" android:text="FAILURE REASONS" android:textAppearance="?android:attr/textAppearanceMedium" android:textColor="#000000" /> < LinearLayout android:id="@+id/failure_reasonslist" android:layout_width="match_parent" android:layout_height="wrap_content" android:focusable="false" android:focusableInTouchMode="false" android:orientation="vertical" > < CheckBox android:id="@+id/failure_Sound" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textColor="#000000" /> < CheckBox android:id="@+id/failure_GPS" android:layout_width="wrap_content" android:layout_height="wrap_content" android:focusable="false" android:focusableInTouchMode="false" android:textColor="#000000" /> < CheckBox android:id="@+id/failure_Display" android:layout_width="wrap_content" android:layout_height="wrap_content" android:focusable="false" android:focusableInTouchMode="false" android:textColor="#000000" /> < CheckBox android:id="@+id/failure_Network" android:layout_width="wrap_content" android:layout_height="wrap_content" android:focusable="false" android:focusableInTouchMode="false" android:textColor="#000000" /> < CheckBox android:id="@+id/failure_Rotation" android:layout_width="wrap_content" android:layout_height="wrap_content" android:focusable="false" android:focusableInTouchMode="false" android:textColor="#000000" /> < CheckBox android:id="@+id/failure_Microphone" android:layout_width="wrap_content" android:layout_height="wrap_content" android:focusable="false" android:focusableInTouchMode="false" android:textColor="#000000" /> < CheckBox android:id="@+id/failure_Others" android:layout_width="wrap_content" android:layout_height="wrap_content" android:focusable="false" android:focusableInTouchMode="false" android:textColor="#000000" /> < /LinearLayout> < /LinearLayout> < LinearLayout android:id="@+id/lineatlayout1" android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="horizontal" > < TextView android:id="@+id/textView2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="DESCRIPTION : " android:textAppearance="?android:attr/textAppearanceMedium" android:textColor="#000000" /> < EditText android:id="@+id/description_text" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_weight="1" android:clickable="true" android:ems="10" android:focusable="true" android:focusableInTouchMode="true" android:inputType="textMultiLine" android:textColor="#000000" > < /EditText> < /LinearLayout> < LinearLayout android:id="@+id/lineatlayout2" android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="horizontal" > < Button android:id="@+id/submit_btn" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="SUBMIT " /> < Button android:id="@+id/uninstall_btn" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="UNINSTALL" /> < /LinearLayout> < !-- < /RelativeLayout> --> < /LinearLayout>

但是根据新要求，我们需要动态添加复选框。就像需要从API调用中获取选项并将其转换为视图中的复选框一样。我花了很多时间。有人可以建议一种方法来解决这个问题。
我们的布局应该是这样的。在列表视图中，我们显示员工详细信息，并且对于每个员工记录，应从API调用或数据库加载限定条件。

[Reviewer Name (Editable)] Employee Lest --------------------------------------- Employee1[Click Me]Male (0)Female ( ) Salary : [5999 (editable)] Qualification [X]BA [ ]BSc [ ]Matriculation [ ]Other [Submit Button] --------------------------------------- Employee2[Click Me]Male (0)Female ( ) Salary : [5999 (editable)] Qualification [X]BA [ ]BSc [ ]Matriculation [ ]Other [Submit Button] --------------------------------------- Employee3[Click Me]Male (0)Female ( ) Salary : [5999 (editable)] Qualification [X]BA [ ]BSc [ ]Matriculation [ ]Other [Submit Button] ---------------------------------------

源代码

private class ListAdapters extends ArrayAdapter< ApplicationBean> { private ArrayList< ApplicationBean> items; private int position; public ListAdapters(Context context, int textViewResourceId, ArrayList< ApplicationBean> mTitleList) { super(context, textViewResourceId, mTitleList); this.items = mTitleList; }@Override public View getView(int position, View convertView, ViewGroup parent) { View v = convertView; this.position = position; if (v == null) { LayoutInflater inflater = (LayoutInflater) mContext .getSystemService(Context.LAYOUT_INFLATER_SERVICE); v = inflater.inflate(R.layout.applicationlistitem, null); }final ApplicationBean o = (ApplicationBean) items.get(position); if (o != null) {txtAppName = (TextView) v.findViewById(R.id.app_name); txtAppName.setText("" + o.getAppName()); launchButton = (Button) v.findViewById(R.id.launch_btn); launchButton.setTag(position); launchButton.setOnClickListener(new OnClickListener() {@Override public void onClick(View v) {final PackageManager pm = mContext.getPackageManager(); Intent LaunchIntent = pm .getLaunchIntentForPackage(items .get(Integer.parseInt(v.getTag() .toString())).getPname()); mContext.startActivity(LaunchIntent); } }); final LinearLayout failure_reasonslist = (LinearLayout) v .findViewById(R.id.failure_reasonslist); rdgPassFail = (RadioGroup) v.findViewById(R.id.status_group); rdgPassFail.setTag(position); RadioButton passBtn = (RadioButton) v .findViewById(R.id.pass_btn); passBtn.setTag(position); RadioButton failbtn = (RadioButton) v .findViewById(R.id.fail_btn); failbtn.setTag(position); rdgPassFail .setOnCheckedChangeListener(new OnCheckedChangeListener() {@Override public void onCheckedChanged(RadioGroup group, int checkedId) { ApplicationBean o = (ApplicationBean) items .get(Integer.parseInt(group.getTag() .toString())); switch (checkedId) { case R.id.fail_btn: Log.e("Fail button", "Clicked"); o.setFailState(true); o.setPassState(false); numOptions = 0; Log.e("Fail button--1", "Clicked"); break; case R.id.pass_btn: Log.e("Pass button", "Clicked"); o.setFailState(false); o.setPassState(true); Log.e("Pass button-----1", "Clicked"); break; } items.set(Integer.parseInt(group.getTag() .toString()), o); }}); LinearLayout featuresTable = (LinearLayout) v.findViewById(R.id.failure_reasonslist); // use loop CheckBox feature1 = new CheckBox(this); for(int i = 0; i< =5; i++) { CheckBox feature1 = new CheckBox(this.getContext()); featuresTable.addView(feature1); }txtDescription = (EditText) v .findViewById(R.id.description_text); txtDescription.setTag(position); if (txtDescription.isFocused()) { InputMethodManager inputManager = (InputMethodManager) mContext .getSystemService(INPUT_METHOD_SERVICE); inputManager.restartInput(txtDescription); }txtDescription .setOnFocusChangeListener(new View.OnFocusChangeListener() {@Override public void onFocusChange(View v, boolean hasFocus) { if (!hasFocus) {final EditText Caption = (EditText) v; o.setDescription(Caption.getText() .toString()); }} }); uninstallButton = (Button) v.findViewById(R.id.uninstall_btn); uninstallButton.setTag(position); // uninstallButton.setVisibility(View.INVISIBLE); o.setUninstallVisible(false); uninstallButton.setOnClickListener(new OnClickListener() {@Override public void onClick(View v) { Uri packageUri = Uri.parse("package:" + items.get( Integer.parseInt(v.getTag().toString())) .getPname()); Intent uninstallIntent = new Intent( Intent.ACTION_DELETE, packageUri); uninstallIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); startActivity(uninstallIntent); mTitleList.remove(items.get((Integer) v.getTag())); mListView.setAdapter(new ListAdapters(mContext, R.id.app_name, mTitleList)); ((BaseAdapter) mListView.getAdapter()) .notifyDataSetChanged(); isUninstallclicked = true; } }); submitButton = (Button) v.findViewById(R.id.submit_btn); submitButton.setTag(txtDescription); submitButton.setOnClickListener(new OnClickListener() {@Override public void onClick(View v) { // TODO Auto-generated method stub EditText tv = (EditText) v.getTag(); // get edittext // objecttxtDescription = tv; if (txtTesterName.getText().toString().equals("")) { showDialog("Please enter the name of tester", mContext); } else if (numOptions == 0) { showDialog("Please select failure reason", mContext); } else if (tv.getText().toString().equals("")) { showDialog("Please enter the description", mContext); } else if (!isNetworkAvailable()) {showDialog( "No network connection.Report won't be submitted", mContext); } else {if (!o.isUninstallVisible()) { uninstallButton.setVisibility(View.VISIBLE); o.setUninstallVisible(true); mListView.invalidate(); } PostRequest p = new PostRequest(Integer.parseInt(tv .getTag().toString())); p.execute(); } }}); } return v; }

答案

LinearLayout featuresTable = (LinearLayout) findViewById(R.id.failure_reasonslist); // use loop CheckBox feature1 = new CheckBox(this); featuresTable.addView(feature1 );

另一答案动态添加CheckBox

LinearLayout my_layout = (LinearLayout)findViewById(R.id.my_layout); // Add Checkbox Dynamically CheckBox checkBox = new CheckBox(mContext); checkBox.setText(ETnewcheckbox.getText().toString()+""); checkBox.setLayoutParams(new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT)); checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { @Override public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { String msg = "You have " + (isChecked ? "checked" : "unchecked") + " this Check it Checkbox."; Toast.makeText(MainActivity.this, msg, Toast.LENGTH_SHORT).show(); } }); // Add Checkbox to LinearLayout if (my_layout != null) { my_layout.addView(checkBox); }

另一答案试试这个。

LinearLayout lLayout = (LinearLayout)findViewById(R.id.yourMainLayout); CheckBox checkBox = new CheckBox(this); // Here you will create CheckBox as many number of Checkbox you want. lLayout.addView(checkBox); // Here you have to add this CheckBox to your layout.
