这种方法应该只能对当前Activity本身进行截屏,因而你只能在你应用程序中参照该代码对其应用程序本身截屏。 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.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 view = activity.getWindow().getDecorView(); view.setDrawingCacheEnabled(true); view.buildDrawingCache(); Bitmap b1 = view.getDrawingCache(); activity.getWindow().getDecorView().getWindowVisibleDisplayFrame(frame); int statusBarHeight = frame.top; Log.i("TAG", "" + statusBarHeight); int width = activity.getWindowManager().getDefaultDisplay().getWidth(); int height = activity.getWindowManager().getDefaultDisplay() // Bitmap b = Bitmap.createBitmap(b1, 0, 25, 320, 455); Bitmap b = Bitmap.createBitmap(b1, 0, statusBarHeight, width, height view.destroyDrawingCache(); private static void savePic(Bitmap b, String strFileName) { FileOutputStream fos = null; fos = new FileOutputStream(strFileName); b.compress(Bitmap.CompressFormat.PNG, 90, fos); } catch (FileNotFoundException e) { } catch (IOException e) { public static void shoot(Activity a) { ScreenShot.savePic(ScreenShot.takeScreenShot(a), "sdcard/xx.png"); 注意:
shoot方法只能在view已经被加载后方可调用。 转载地址:http://rqrdi.baihongyu.com/
