程序代码如下：

Java代码

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);
}
}
