Android 截屏小程序

先看截图，不过这个截屏还不够完整，头上的statusbar没有，呈黑色。

多按了几次，就成这样了，呵呵。

package com.test;

import android.app.Activity;
import android.graphics.Bitmap;
import android.graphics.Canvas;
import android.graphics.Bitmap.Config;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.ImageView.ScaleType;

public class ScreenPrinter extends Activity {
/** Called when the activity is first created. */
boolean customTitleSupported;

public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.screen_printer);
  Button btn = (Button)findViewById(R.id.btn);
  btn.setOnClickListener(new Button.OnClickListener(){
   public void onClick(View arg0) {
    ImageView im = (ImageView)findViewById(R.id.img);

    Bitmap bmp = Bitmap.createBitmap(320, 480, Config.ARGB_8888);
    View cv = getWindow().getDecorView();
    cv.draw(new Canvas(bmp));
    im.setScaleType(ScaleType.FIT_XY);
    im.setImageBitmap(bmp);
   }});
}
}
