关于Android如何获取屏幕分辨率的例子

Android如何获取屏幕分辨率的例子程序代码如下：

package com.acquire.resolution;     
  
 
import android.app.Activity;  
import android.content.res.Resources;  
import android.graphics.Color;  
import android.graphics.drawable.Drawable;  
import android.os.Bundle;  
import android.util.DisplayMetrics;  
import android.widget.TextView;  
 
public class AcquireResolution extends Activity {  
    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
        setContentView(R.layout.main);      
        TextView tv = (TextView)findViewById(R.id.textView);  
        Resources resources = getBaseContext().getResources();  
        Drawable drawable = resources.getDrawable(R.drawable.red);  
        tv.setBackgroundDrawable(drawable);  
        tv.setTextColor(Color.GREEN);    
        DisplayMetrics dm = new DisplayMetrics();  
        getWindowManager().getDefaultDisplay().getMetrics(dm);  
        tv.setText("屏幕分辨率为:"+dm.widthPixels+" * "+dm.heightPixels);  
          
          
    }  
} 
package com.acquire.resolution;

import android.app.Activity;
import android.content.res.Resources;
import android.graphics.Color;
import android.graphics.drawable.Drawable;
import android.os.Bundle;
import android.util.DisplayMetrics;
import android.widget.TextView;

public class AcquireResolution extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);   
        TextView tv = (TextView)findViewById(R.id.textView);
        Resources resources = getBaseContext().getResources();
        Drawable drawable = resources.getDrawable(R.drawable.red);
        tv.setBackgroundDrawable(drawable);
        tv.setTextColor(Color.GREEN); 
        DisplayMetrics dm = new DisplayMetrics();
        getWindowManager().getDefaultDisplay().getMetrics(dm);
        tv.setText("屏幕分辨率为:"+dm.widthPixels+" * "+dm.heightPixels);
       
       
    }
}

运行结果如下：
