android imagebutton的使用

ImageButton是上面带有图片的Button，与Button只用类似

第一步：

首先找到两个图标，在res目录下创建一个名为drawable的文件夹，将图片放入其中

第二步：

编写main.xml文件，如下

<?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"
    >
<ImageButton
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
<ImageButton
android:id="@+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
</LinearLayout>

第三步：

编写ButtonActivity.java文件

package org.loulijun.buttonTest;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ImageButton;
import android.widget.LinearLayout;

public class ButtonActivity extends Activity implements OnClickListener {
    /** Called when the activity is first created. */
ImageButton button1;
ImageButton button2;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
       
        button1=(ImageButton)findViewById(R.id.button1);
        button1.setImageResource(R.drawable.icon1);
        button1.setVisibility(View.VISIBLE);
       
        button2=(ImageButton)findViewById(R.id.button2);
        button2.setImageResource(R.drawable.icon2);
        button2.setVisibility(View.GONE);
       
        button1.setOnClickListener(this);
        button2.setOnClickListener(this);
    }
@Override
public void onClick(View v) {
  // TODO Auto-generated method stub
   switch(v.getId())
   {
   case R.id.button1:
    button1.setVisibility(View.GONE);//隐藏ImageButton1
    button2.setVisibility(View.VISIBLE);//显示ImageButton2
    break;
   case R.id.button2:
    button1.setVisibility(View.VISIBLE);
    button2.setVisibility(View.GONE);
    break;
    default:break;
   }
}
}
