关于android如何获取屏幕分辨率的例子

程序代码如下：

packagecom.acquire.resolution;



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

publicclassAcquireResolutionextendsActivity{
/**Calledwhentheactivityisfirstcreated.*/
@Override
publicvoidonCreate(BundlesavedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TextViewtv=(TextView)findViewById(R.id.textView);
Resourcesresources=getBaseContext().getResources();
Drawabledrawable=resources.getDrawable(R.drawable.red);
tv.setBackgroundDrawable(drawable);
tv.setTextColor(Color.GREEN);
DisplayMetricsdm=newDisplayMetrics();
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);
        
        
    }
