本文提供了一个使用Java编程语言实现的功能，用于在Android应用中获取屏幕的分辨率，并将其显示在界面上。

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);
}
}

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); }
