安卓界面跳转 _安卓

大鹏一日同风起，扶摇直上九万里。这篇文章主要讲述安卓界面跳转相关的知识，希望能为你提供帮助。

界面设计代码

< ?xml version="1.0" encoding="utf-8"?> < LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/activity_tiaozhuan" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@android:color/holo_orange_dark" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" android:orientation="vertical" tools:context="hello.jmtiaozhuan.TiaozhuanActivity"> < EditText android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginTop="150dp" android:hint="@string/EditTextname" android:textColorHint="#f0ff" android:gravity="center" android:textColor="#00ffee" android:id="@+id/shuru"/> < LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content"> < Button android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="1" android:text="@string/button1" style="@style/text" android:onClick="onClick" android:id="@+id/button1"/> < Button android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="1" android:text="@string/button2" style="@style/text" android:id="@+id/button2"/> < /LinearLayout> < TextView android:layout_width="match_parent" android:layout_height="wrap_content" android:text="@string/TextViewname" android:gravity="center" android:id="@+id/show" android:textColor="#33ff00" style="@style/text" android:onClick="onClick"/> < /LinearLayout>

效果如下

string文件代码

< resources> < string name="app_name"> JMtiaozhuan< /string> < string name="button1"> 点击进入评估< /string> < string name="button2"> 退出< /string> < string name="EditTextname"> 请输入您的姓名< /string> < string name="TextViewname"> 输出评估结果< /string> < string name="button3"> 有< /string> < string name="button4"> 没有< /string> < /resources>
重点内容按钮监控

btbutton2.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { if (btbutton2.isClickable()) { Toast.makeText(MainbackActivity.this, "再按一次退出按钮", Toast.LENGTH_LONG).show(); //如果退出按钮被点击一下，会显示文本再按一次退出按钮 btbutton2.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { if (btbutton2.isClickable()) { MainbackActivity.this.finish(); //再一次监听按钮，如果再按一次退出按钮，就会关闭整个界面 } } }); } } });

最重要数据传递
1主界面向子界面传递数据

if (TextUtils.isEmpty(etshuru.getText().toString())) { Toast.makeText(MainbackActivity.this, "输入名称不能为空", Toast.LENGTH_SHORT).show(); //如果没有输入名字就点击进入评估的话就会显示 return; } String name = etshuru.getText().toString(); Intent mIntent = new Intent(MainbackActivity.this, JiemianActivity.class); mIntent.putExtra("name", etshuru.getText().toString().trim() + "同学：学习Android有没有信心?"); //将name字符串传递给子界面，trim（）为去掉两边的空格 startActivityForResult(mIntent, 1000);

2子界面接收数据

Intent intent = getIntent(); TextView tvshow=(TextView)findViewById(R.id.show); String name=intent.getStringExtra("name"); //接收主界面传递过来的name数据 tvshow.setText(name);

3子界面返回数据

private void ruturn() { Intent intent=new Intent(this,MainbackActivity.class); Button btnbutton3=(Button)findViewById(R.id.button3); String name=btnbutton3.getText().toString(); intent.putExtra("name","评估内容返回为："+name); finish(); }

4主界面接受返回数据

protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); //使用onActivityResult(int requestCode, int resultCode, Intent data)获取data if (requestCode == 1000 & & (resultCode == 1001 || resultCode == 1002)) {//使主界面的requestCode1000和子界面的resultCode1001或者1002比较 TextView tvshow = (TextView) findViewById(R.id.show); String result = data.getStringExtra("name"); //接收子界面传递的"name"数据 tvshow.setText(result); } }
