android include使用[转]
需要包含的xml文件,我这里就放了一个Button按钮:
btn.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="wrap_content"
- android:orientation="vertical" >
- <Button
- android:id="@+id/btn"
- android:layout_width="wrap_content"
- android:layout_height="wrap_content"
- android:text="Button">
- </Button>
- </LinearLayout>
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"
- >
- <include android:id="@+id/in1" layout="@layout/btn"/>
- <include android:id="@+id/in2" layout="@layout/btn"/>
- <TextView android:id="@+id/tv"
- android:layout_width="fill_parent"
- android:layout_height="wrap_content"
- android:text="@string/hello" />
- </LinearLayout>
TestActivity:
- package com.hilary;
- import android.app.Activity;
- import android.graphics.Color;
- import android.os.Bundle;
- import android.view.View;
- import android.view.View.OnClickListener;
- import android.widget.Button;
- import android.widget.LinearLayout;
- import android.widget.TextView;
- import com.hialry.R;
- /**

- *@author:hilary

- *@description:

- **/
- public class TestActivity extends Activity {
- private TextView tv = null;
- private LinearLayout ll = null;
- private LinearLayout ll2 = null;
- /** Called when the activity is first created. */
- @Override
- public void onCreate(Bundle savedInstanceState) {
- super.onCreate(savedInstanceState);
- setContentView(R.layout.main);
- tv = (TextView) findViewById(R.id.tv);
- //如果一个布局文件中包含同一个xml文件,这两个xml中的控件Id是一样的,当需要操作这些控件时,需要通过定义这两个View来加以区分,
- //如果就包含同一个xml文件侧不需要此步操作
- ll = (LinearLayout) findViewById(R.id.in1);
- ll2 = (LinearLayout) findViewById(R.id.in2);
- ll.setBackgroundColor(Color.RED);
- Button btn = (Button) ll.findViewById(R.id.btn);
- btn.setOnClickListener(new OnClickListener() {
- @Override
- public void onClick(View v) {
- tv.setText("My name is hilary");
- }
- });
- Button btn2 = (Button) ll2.findViewById(R.id.btn);
- btn2.setOnClickListener(new OnClickListener() {
- @Override
- public void onClick(View v) {
- tv.setText(" You select second Button!");
- }
- });
- }
- }
这只是在xml文件中引入另一种布局的一种方法,我们还可以在代码中直接引入,而不需要在xml中定义要引入的文件,在这里就不多说了
