import java.io.FileNotFoundException;import java.io.FileOutputStream;import java.io.IOException;import android.app.Activity;import android.graphics.Bitmap;import android.graphics.Rect;import android.util.Log;import android.view.View;public class ScreenShot { // 获取指定Activity的截屏,保存到png文件 private static Bitmap takeScreenShot(Activity activity) { // View是你需要截图的View View view = activity.getWindow().getDecorView(); view.setDrawingCacheEnabled(true); view.buildDrawingCache(); Bitmap b1 = view.getDrawingCache(); // 获取状态栏高度 Rect frame = new Rect(); activity.getWindow().getDecorView().getWindowVisibleDisplayFrame(frame); int statusBarHeight = frame.top; Log.i("TAG", "" + statusBarHeight); // 获取屏幕长和高 int width = activity.getWindowManager().getDefaultDisplay().getWidth(); int height = activity.getWindowManager().getDefaultDisplay() .getHeight(); // 去掉标题栏 // Bitmap b = Bitmap.createBitmap(b1, 0, 25, 320, 455); Bitmap b = Bitmap.createBitmap(b1, 0, statusBarHeight, width, height - statusBarHeight); view.destroyDrawingCache(); return b; } // 保存到sdcard private static void savePic(Bitmap b, String strFileName) { FileOutputStream fos = null; try { fos = new FileOutputStream(strFileName); if (null != fos) { b.compress(Bitmap.CompressFormat.PNG, 90, fos); fos.flush(); fos.close(); } } catch (FileNotFoundException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } } // 程序入口 public static void shoot(Activity a) { ScreenShot.savePic(ScreenShot.takeScreenShot(a), "sdcard/xx.png"); }} 需要注意的是,shoot方法只能在view已经被加载后方可调用。或者在 @Override public void onWindowFocusChanged(boolean hasFocus) { // TODO Auto-generated method stub super.onWindowFocusChanged(hasFocus); ScreenShot.shoot(this); }中调用
