話就不多說了，直接上代碼。
二、源碼
步驟一、在根目錄下建立 drawable檔案夾，然後在drawable裡建立clip_btimap.xml
| 代碼如下 |
複製代碼 |
<?xml version="1.0" encoding="utf-8"?>
<clip xmlns:android="http://schemas.android.com/apk/res/android"
android:clipOrientation="horizontal"
android:drawable="@drawable/t2"
android:gravity="left|start" >
</clip> |
步驟二、activity_main.xml
| 代碼如下 |
複製代碼 |
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/t1" />
<ImageView
android:id="@+id/iv_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/clip_btimap" />
</FrameLayout> |
步驟三、MainActivity
| 代碼如下 |
複製代碼 |
package com.msquirrel.main;
import java.util.Timer;
import java.util.TimerTask;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.app.Activity;
import android.graphics.drawable.ClipDrawable;
import android.view.Menu;
import android.widget.ImageView;
/**
*
* 入口類
* @author Msquirrel
*
*/
public class MainActivity extends Activity {
private ImageView imageView = null;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
imageView = (ImageView)findViewById(R.id.iv_image);
//擷取圖片所顯示的ClipDrawble對象
final ClipDrawable drawable = (ClipDrawable)imageView.getDrawable();
final Handler handler = new Handler()
{
public void handleMessage(Message msg)
{
if(msg.what == 0x1233)
{
if(drawable.getLevel() >= 10000){
drawable.setLevel(0);
}
//修改ClipDrawable的level值
drawable.setLevel(drawable.getLevel() +500);
}
}
};
//時間類
final Timer timer = new Timer();
timer.schedule(new TimerTask()
{
public void run()
{
Message msg = new Message();
msg.what = 0x1233;
//發送訊息,通知應用修改ClipDrawable對象的level值
handler.sendMessage(msg);
//取消定時器
// if(drawable.getLevel() >= 10000)
// {
// timer.cancel();
// }
}
},0,300);
}
}
