私は数時間前にこの問題を抱えていました(Android:AsyncTask、他のタスクが開始したときに最初のタスクが終了していません)解決したと思いますが、同様の問題があることに気付きました。
これが私のメインクラス「GameActivity」です
public void mainmethod()
Log.w("GAMEACTIVITY","actionup");
myAsyncRunnable mar = new myAsyncRunnable(GameActivity.this);
mar.execute("fire");
public void doPhotoTask() {
PhotoTask photoTask = new PhotoTask(camera,surfaceCamera,isPreview,holder,GameActivity.this);
photoTask.execute(null);
}
myAsyncRunnable.fire()で、gameActivityのImageViewの画像の10倍を超える変化をするループがあります。最後の画像が変更されたときにphotoTaskを開始したいここでmyAsyncRunnableのコードはAsyncTaskを拡張します
@Override
protected Void doInBackground(String... params) {
fire();
return null;
}
public void fire() {
final ImageView image3 = (ImageView) gameactivity.findViewById(R.id.imageView3);
final int drawables[] = new int[] {R.drawable.fire1,R.drawable.fire2,R.drawable.fire3,R.drawable.fire4,R.drawable.fire5,R.drawable.fire6,R.drawable.fire7,R.drawable.fire8,R.drawable.fire9,R.drawable.fire10,R.drawable.fire11,R.drawable.fire12,R.drawable.fire13,R.drawable.fire14,R.drawable.fire15,R.drawable.fire16};
for (int i=0;i<drawables.length;i++) {
final int j=i;
Runnable runnable = new Runnable() {
@Override
public void run() {
image3.setImageResource(drawables[j]);
Log.w("GAMEACTIVITY","image"+j);
}
};
gameactivity.handler.postDelayed(runnable, 200*j);
}
}
@Override
protected void onPostExecute(Void result) {
Log.w("GAMEACTIVITY","ONPOSTEXECUTE");
gameactivity.doPhotoTask();
}
PhotoTaskで
@Override
protected Void doInBackground(Boolean... params) {
camera.takePicture(null,null, myPictureCallback_JPG);
Log.w("GAMEACTIVITY","TAKEPICTURE");
return null;
}
