转载：如何截取屏幕大小信息

转载自：www.madhome.org

要获得屏幕大小信息，我是从一个Activity调用：

Java:

DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
int height = dm.heightPixels;
int width = dm.widthPixels;

 

另一种方法：

Java:

package de.android.screentest;

import de.android.screentest.R;
import android.app.Activity;
import android.os.Bundle;
import android.widget.LinearLayout;
import android.graphics.Color;
import android.graphics.drawable.Drawable;
import android.widget.TextView;
import android.view.Display;

import android.view.WindowManager;

public class ScreenTest extends Activity
{    
     private LinearLayout main;
     private TextView tv;
     
     Display display;
     
     String txt;
     
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
       
        main = new LinearLayout(this);
        main.setBackgroundColor(Color.BLACK);
        main.setOrientation(LinearLayout.VERTICAL);
       
        tv = new TextView(this);
        tv.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,LinearLayout.LayoutParams.WRAP_CONTENT));
        tv.setText(getScreenProps());
        main.addView(tv);
       
        setContentView(main);
    }
   
    private String getScreenProps()
    {
     String s = "screen property: ";
     
     display = ((WindowManager)getSystemService(WINDOW_SERVICE)).getDefaultDisplay();
     
     int height = display.getHeight();
     int width = display.getWidth();
     
     s = s + width + " " + height;
     
     return s;
    }
