关于android如何获取屏幕分辨率的例子

程序代码如下：

Java代码

1. package com.acquire.resolution;  
2.   
3.   
4.   
5. import android.app.Activity;  
6. import android.content.res.Resources;  
7. import android.graphics.Color;  
8. import android.graphics.drawable.Drawable;  
9. import android.os.Bundle;  
10. import android.util.DisplayMetrics;  
11. import android.widget.TextView;  
12.   
13. public class AcquireResolution extends Activity {  
14.     /** Called when the activity is first created. */  
15.     @Override  
16.     public void onCreate(Bundle savedInstanceState) {  
17.         super.onCreate(savedInstanceState);  
18.         setContentView(R.layout.main);      
19.         TextView tv = (TextView)findViewById(R.id.textView);  
20.         Resources resources = getBaseContext().getResources();  
21.         Drawable drawable = resources.getDrawable(R.drawable.red);  
22.         tv.setBackgroundDrawable(drawable);  
23.         tv.setTextColor(Color.GREEN);    
24.         DisplayMetrics dm = new DisplayMetrics();  
25.         getWindowManager().getDefaultDisplay().getMetrics(dm);  
26.         tv.setText("屏幕分辨率为:"+dm.widthPixels+" * "+dm.heightPixels);  
27.           
28.           
29.     }  
30. }
