android开发 include如何获取内部控件

在某个xml中有多个设置了id的控件，新建一个xml在include后，如何获取include之后的内部的控件并对其属性进行修改呢？

Answer 1

1. 直接对include部分的源文件布局做调整
2. 通过代码findViewById()做调整.

追问

findViewById的方法也是相当于对源文件的布局做了调整，include不是相当于将原先的xml的布局copy到新的xml中吗？我是想原先的布局无变动，include后添加一些属性

追答

目前还没有听说include这样的功能,如果非要在xml里面改的话,给你个笨方法,就是在做一个include部分的layout,放入一个新文件中,对其做你要的改动.虽然方法笨拙,但是这样不违背的你的初衷了.

Answer 2

android开发 include获取内部控件代码：
sublayout.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#505050"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="SubLayout"
/>
<Button
android:id="@+id/mybutton"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text=" A Button "
/>
</LinearLayout>

mail.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/hello"
/>
<include android:id="@+id/main1" layout="@layout/sublayout" />
<include android:id="@+id/main2" layout="@layout/sublayout" />
<Button
android:id="@+id/startanotheractivity"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text=" Start Another Activity "
/>
</LinearLayout>

如何调用组件include进来的组件呢。

package com.AndroidIncludeLayout;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

public class AndroidIncludeLayout extends Activity {

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

View subLayout1 = (View)findViewById(R.id.main1);
View subLayout2 = (View)findViewById(R.id.main2);
Button myButton_main1 = (Button)subLayout1.findViewById(R.id.mybutton);
Button myButton_main2 = (Button)subLayout2.findViewById(R.id.mybutton);
Button startAnotherActivity = (Button)findViewById(R.id.startanotheractivity);

startAnotherActivity.setOnClickListener(new Button.OnClickListener(){

@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
Intent intent = new Intent();
intent.setClass(AndroidIncludeLayout.this, AnotherActivity.class);
startActivity(intent);

}});

myButton_main1.setOnClickListener(new Button.OnClickListener(){

@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
Toast.makeText(AndroidIncludeLayout.this, "Button 1 Pressed", Toast.LENGTH_LONG).show();
}});

myButton_main2.setOnClickListener(new Button.OnClickListener(){

@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
Toast.makeText(AndroidIncludeLayout.this, "Button 2 Pressed", Toast.LENGTH_LONG).show();
}});
}
}
