历览千载书，时时见遗烈。这篇文章主要讲述在android中动态添加按钮的问题相关的知识，希望能为你提供帮助。
动态添加按钮的问题，如何让按钮自动进入下一行
像这样：
我想要的输出：

我得到的输出：

这是我的代码：

LinearLayout ll = (LinearLayout)view.findViewById(R.id.layout); Button btn = new Button(getContext()); btn.setText("Button1"); btn.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT)); Button btn1 = new Button(getContext()); btn1.setText("Button2"); btn1.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT)); Button btn2 = new Button(getContext()); btn2.setText("Button3"); btn2.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT)); Button btn3 = new Button(getContext()); btn3.setText("Button4"); btn3.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT)); Button btn4 = new Button(getContext()); btn4.setText("Button5"); btn4.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT)); ll.addView(btn); ll.addView(btn1); ll.addView(btn2); ll.addView(btn3); ll.addView(btn4);

在XML中：

< LinearLayout android:orientation="horizontal" android:id="@+id/layout" android:layout_width="match_parent" android:layout_height="wrap_content"> < /LinearLayout>

我是Android新手，谢谢大家:)
答案使用我新设计的PredicateLayout来自动将按钮移动到下一行，如下所示
XML

< PredicateLayout android:orientation="horizontal" android:id="@+id/layout" android:layout_width="match_parent" android:layout_height="wrap_content"/>

java的

PredicateLayout ll = (PredicateLayout)view.findViewById(R.id.layout); Button btn = new Button(getContext()); btn.setText("Button1"); btn.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT)); Button btn1 = new Button(getContext()); btn1.setText("Button2"); btn1.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT)); Button btn2 = new Button(getContext()); btn2.setText("Button3"); btn2.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT)); Button btn3 = new Button(getContext()); btn3.setText("Button4"); btn3.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT)); Button btn4 = new Button(getContext()); btn4.setText("Button5"); btn4.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT)); ll.addView(btn); ll.addView(btn1); ll.addView(btn2); ll.addView(btn3); ll.addView(btn4);

另一答案【在android中动态添加按钮的问题】请将LinearLayout方向设置为垂直

< LinearLayout android:orientation="vertical" android:id="@+id/layout" android:layout_width="match_parent" android:layout_height="wrap_content"> < /LinearLayout>

另一答案

LinearLayout linearLayoutSubParent = new LinearLayout(AddNewContactActivity.this); linearLayoutSubParent.setOrientation(LinearLayout.HORIZONTAL); linearLayoutSubParent.setWeightSum(100f); LinearLayout.LayoutParams linearLayoutSubParentParams = new LinearLayout.LayoutParams(0, LinearLayout.LayoutParams.WRAP_CONTENT, 90f); // youcan add multiple view, by providing weight. linearLayoutSubParent.setLayoutParams(linearLayoutSubParentParams); linearLayoutSubParent.setPadding(0, 0, 0, 0); final Button button = new Button(this); LinearLayout.LayoutParams editTextParams = new LinearLayout.LayoutParams( LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT); editTextParams.setMargins(0, 10, 0, 0); button.setLayoutParams(editTextParams); button.setTextSize(TypedValue.COMPLEX_UNIT_PX, getResources().getDimension(R.dimen.list_item_Big_text_size)); button.setText("Text"); button.setInputType(InputType.TYPE_TEXT_FLAG_CAP_WORDS); button.setEnabled(false); linearLayoutSubParent.addView(button); linearLayoutParent.addView(linearLayoutSubParent); < LinearLayout android:id="@+id/linearLayoutParent" android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical" > < /LinearLayout>
