這種方法應該只能對當前Activity本身進行截屏,因而你只能在你應用程式中參照該代碼對其應用程式本身截屏。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.util.Log;import android.view.View; public class ScreenShot { // 擷取指定Activity的截屏,儲存到png檔案 private static Bitmap takeScreenShot(Activity activity) { // View是你需要的View View view = activity.getWindow().getDecorView(); view.setDrawingCacheEnabled(true); view.buildDrawingCache(); Bitmap b1 = view.getDrawingCache(); // 擷取狀態列高度 Rect frame = new Rect(); activity.getWindow().getDecorView().getWindowVisibleDisplayFrame(frame); int statusBarHeight = frame.top; Log.i("TAG", "" + statusBarHeight); // 擷取螢幕長和高 int width = activity.getWindowManager().getDefaultDisplay().getWidth(); int height = activity.getWindowManager().getDefaultDisplay() .getHeight(); // 去掉標題列 // Bitmap b = Bitmap.createBitmap(b1, 0, 25, 320, 455); Bitmap b = Bitmap.createBitmap(b1, 0, statusBarHeight, width, height - statusBarHeight); view.destroyDrawingCache(); return b; } // 儲存到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(); } } // 程式入口 public static void shoot(Activity a) { ScreenShot.savePic(ScreenShot.takeScreenShot(a), "sdcard/xx.png"); }}
注意:shoot方法只能在view已經被載入後方可調用。
