Question

我有这样的数据

 <LinearLayout> ===> vertical
     <LinearLayout> ===>Horizontal
       <TextView>    <TextView>  <TextView>    <TextView>
    <LinearLayout> ===>Horizontal
      <TextView>    <TextView>  <TextView>    <TextView>
    <LinearLayout> ===>Horizontal
      <TextView>    <TextView>  <TextView>    <TextView>

 <LinearLayout>

如何动态添加这些布局？

谢谢

Answer 1

我会帮助你完成我所做的代码。请注意，我不会为您编码（现在仍然帮助某人来自SO）。如果您有任何疑问，请随意。

在这里，我在spinner的{{1}}上添加了button和linear layout，这些都是动态的：

onClick

这就是我检索else if(v == btnAddChild) { LinearLayout dynamicLayout = new LinearLayout(this); LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT); params.weight = 1.0f; params.gravity = Gravity.CENTER_VERTICAL; dynamicLayout.setLayoutParams(params); dynamicLayout.setOrientation(LinearLayout.HORIZONTAL); int layoutId = totalDynamicChild + 1000; //dynamicLayout always have dynamic spinnser's id + 1000 to avoid same id dynamicLayout.setId(layoutId); Spinner spinner = new Spinner(this); spinner.setLayoutParams(params); spinner.setAdapter(spinChildAdapter); spinner.setId(totalDynamicChild); spinnderIdList.add(totalDynamicChild); ImageButton btn = new ImageButton(this); btn.setImageDrawable(getResources().getDrawable(R.drawable.action_delete)); btn.setBackgroundResource(0); btn.setLayoutParams(params); int btnId = totalDynamicChild + 2000; //btn always have dynamic spinnser's id + 2000 to avoid same id btn.setId(btnId); dynamicLayout.addView(spinner); dynamicLayout.addView(btn); parentSpinner.addView(dynamicLayout); totalDynamicChild++;值的方法：

spinner's

使用ScrollView作为父级为垂直LinearLayout创建一个xml，因此每当LinearLayout no of child更多时，它将应用scroll。

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical">

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

    </LinearLayout>
</ScrollView>

另一个垂直LinearLayout子级的xml，它在Horizontal LinearLayout中包含4个TextView。

<TextView
    android:id="@+id/textView1"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_weight="1"/>

<TextView
    android:id="@+id/textView2"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_weight="1"/>

<TextView
    android:id="@+id/textView3"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_weight="1"/>

<TextView
    android:id="@+id/textView4"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_weight="1"/>

现在如何将项目添加到垂直LinearLayout：

private LinearLayout container;
private Context context;
private int size=3;
private int counter=1;

context = this;
container = (LinearLayout) findViewById(R.id.container);

for (int i=0;i<size;i++){
     View view  = LayoutInflater.from(context).inflate(R.layout.row_item,null);
     TextView textView1 = (TextView) view.findViewById(R.id.textView1);
     TextView textView2 = (TextView) view.findViewById(R.id.textView2);
     TextView textView3 = (TextView) view.findViewById(R.id.textView3);
     TextView textView4 = (TextView) view.findViewById(R.id.textView4);

     textView1.setText(String.valueOf(counter++));
     textView2.setText(String.valueOf(counter++));
     textView3.setText(String.valueOf(counter++));
     textView4.setText(String.valueOf(counter++));

     view.setTag((i+1));
     view.setOnClickListener(new View.OnClickListener() {
           @Override
           public void onClick(View v) {
              Toast.makeText(context,String.valueOf((Integer)v.getTag()),Toast.LENGTH_SHORT).show();
            }
     });
     container.addView(view);
}

在Android中动态地将线性布局添加到线性布局
