我试图通过代码获取我的游戏截图并通过意图分享.我可以做这些事情,但屏幕截图总是显示为黑色.以下是与共享屏幕截图相关的代码:
View view = MainActivity.getView();
view.setDrawingCacheEnabled(true);
Bitmap screen = Bitmap.createBitmap(view.getDrawingCache(true));
.. save Bitmap
这是在MainActivity中:
view = new GameView(this);
view.setLayoutParams(new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.FILL_PARENT,
RelativeLayout.LayoutParams.FILL_PARENT));
public static SurfaceView getView() {
return view;
}
而观点本身:
public class GameView extends SurfaceView implements SurfaceHolder.Callback {
private static SurfaceHolder surfaceHolder;
...etc
这就是我绘制一切的方式:
Canvas canvas = surfaceHolder.lockCanvas(null);
if (canvas != null) {
Game.draw(canvas);
...
好的,根据一些答案,我构建了这个:
public static void share() {
Bitmap screen = GameView.SavePixels(0, 0, Screen.width, Screen.height);
Calendar c = Calendar.getInstance();
Date d = c.getTime();
String path = …我有一个应用程序,我希望能够捕获屏幕截图
这是我的代码:
public class Screenshot {
private final View view;
/** Create snapshots based on the view and its children. */
public Screenshot(View root) {
this.view = root;
}
/** Create snapshot handler that captures the root of the whole activity. */
public Screenshot(Activity activity) {
final View contentView = activity.findViewById(android.R.id.content);
this.view = contentView.getRootView();
}
/** Take a snapshot of the view. */
public Bitmap snap() {
Bitmap bitmap = Bitmap.createBitmap(this.view.getWidth(), this.view.getHeight(), Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
view.draw(canvas);
return …我希望我的应用能够在不使用其他应用程序的情况下捕获照片.我使用的代码:
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File photo = null;
try
{
photo = this.createTemporaryFile("picture", ".jpg");
photo.delete();
}
catch(Exception e)
{
Toast.makeText(getApplicationContext(),"Error",Toast.LENGTH_LONG).show();
}
mImageUri = Uri.fromFile(photo);
intent.putExtra(MediaStore.EXTRA_OUTPUT, mImageUri);
startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
但此代码使用手机的主要相机应用程序.谁能给我一些代码？
