当我屏幕截图时。我无法成功拍摄全屏幕。只显示路径。 我想知道我的代码问题是什么。我希望有一个人可以帮助我。谢谢
这是我的结果:
// Screen shot
private static Bitmap takeScreenShot(Activity activity) {
// View to shot View
View view = activity.getWindow().getDecorView();
//View view = getPopupViews(getDecorViews())[0];
Log.i("ABC", view.getClass().getName());
view.setDrawingCacheEnabled(true);
view.buildDrawingCache();
Bitmap b1 = view.getDrawingCache();
// the height
Rect frame = new Rect();
view.getWindowVisibleDisplayFrame(frame);
int statusBarHeight = frame.top;
System.out.println(statusBarHeight);
// width and height
int width = activity.getWindowManager().getDefaultDisplay().getWidth();
int height = activity.getWindowManager().getDefaultDisplay().getHeight();
// del the state bar
// Bitmap b = Bitmap.createBitmap(b1, 0, 25, 320, 455);
Bitmap b = Bitmap.createBitmap(b1, 0, statusBarHeight, width, height - statusBarHeight);
view.destroyDrawingCache();
return b;
}
// save image to sdcard
private static void savePic(Bitmap b, String strFileName) {
FileOutputStream fos = null;
try {
fos = new FileOutputStream(strFileName);
if (null != fos) {
b.compress(Bitmap.CompressFormat.JPEG, 90, fos);
fos.flush();
fos.close();
}
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
private void shoot() {
shoot(this);
}
// call function
public static void shoot(Activity a) {
savePic(takeScreenShot(a), "data/data/com.example.map/"+number+".png");
}

尝试此代码,并在此
中传递mapViewpublic final static Bitmap takeScreenShot(View view) {
Bitmap bitmap = Bitmap.createBitmap(view.getWidth(), view.getHeight(), Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
view.draw(canvas);
return bitmap;
}

private Bitmap getMapImage() {
MapController mc = mapView.getController();
mc.setCenter(GEO_POINT);
mc.setZoom(ZOOM_LEVEL);
/* Capture drawing cache as bitmap */
mapView.setDrawingCacheEnabled(true);
Bitmap bmp = Bitmap.createBitmap(mapView.getDrawingCache());
mapView.setDrawingCacheEnabled(false);
return bmp;
}
private void saveMapImage() {
String filename = "SCREEN_SHOT.png";
File f = new File(getExternalFilesDir(null), filename);
FileOutputStream out = new FileOutputStream(f);
Bitmap bmp = getMapImage();
bmp.compress(Bitmap.CompressFormat.PNG, 100, out);
out.close();
}
