Android中多层动态嵌套布局的实现
.下面是一个简单的案例(该案例只是实现了多层嵌套的添加,如果需要实现动态的添加效果,只需通过控制条件改变每次添加的内容即可。)
PadTestActivity.java
package com.devin;
import android.app.Activity;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.widget.LinearLayout;
public class PadTestActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
LayoutInflater inflater=getLayoutInflater();
//Add first page
LinearLayout myFirst = (LinearLayout) inflater.inflate(
R.layout.first, null).findViewById(R.id.myFirst);
LinearLayout layoutMain = (LinearLayout)findViewById(R.id.LayoutMain);
layoutMain.removeAllViews();
layoutMain.addView(myFirst); //Show the page first
//Add second page
LinearLayout mySecond = (LinearLayout) inflater.inflate(
R.layout.second, null).findViewById(R.id.mySecond);
LinearLayout layoutFirst = (LinearLayout) findViewById(R.id.LayoutFirst);
layoutFirst.addView(mySecond);
//Add third page
LinearLayout myThird = (LinearLayout) inflater.inflate(
R.layout.third, null).findViewById(R.id.myThird);
LinearLayout layoutSecond = (LinearLayout) findViewById(R.id.LayoutSecond);
layoutSecond.addView(myThird);
}
}布局代码
main.xml
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Main Page" /> <LinearLayout android:id="@+id/LayoutMain" android:layout_width="fill_parent" android:layout_height="fill_parent" > </LinearLayout> <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Main Page" /></LinearLayout>
