java - 如何摆脱 "has leaked window"？

Question

我已经通过谷歌查看了，但我找到的所有答案都与我的问题无关......

这是我的错误日志

Activity com.fittingroom.newtimezone.view.ActivityAcceptNotAccept has leaked window com.android.internal.policy.PhoneWindow$DecorView{57b68a6 V.ED..... R......D 0,0-324,534} that was originally added here

我正在做的事情，我只是创建进度对话框并在 assynk 任务的控制下，并且在 onPreExecute() 对话框中打开，因此在 onPostExecute() 对话框中关闭...

这是我的代码

public final class ActivityAcceptNotAccept extends Activity implements IActivityAcceptNotAccept {

private Dialog progressDialog;

@Override
protected void onCreate(Bundle savedInstanceState) {
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_accept_not_accept);

    ...///

    presenter.initView();


}

...///

@Override
public void initView() {
    progressDialog = UtilClass.getDialog(ActivityAcceptNotAccept.this, getString(R.string.loading));
}

public final void accept(View view) {
    switch (count) {
        case firstClick:
            presenter.setCroppedPreviewImage();
            break;
        case secondClick:
            presenter.setResultOkAndFinishActivity();
            break;
    }
}

@Override
public void setDisplaySize() {
    UtilClass.setDisplaySize(getWindowManager().getDefaultDisplay(), getWindow(), 95, 95);
}

@Override
public void openProgress() {
    if (progressDialog != null) {
        progressDialog.show();
    }
}

@Override
public void closeProgress() {
    if (progressDialog != null) {
        progressDialog.cancel();
        progressDialog = null;
    }
}
}

有一种方法可以为我提供Dialog实例

public abstract class UtilClass {

public static Dialog getDialog(Context context, String text) {
    final Dialog progressDialog = new Dialog(context);
    progressDialog.setContentView(R.layout.dialog);
    progressDialog.setCanceledOnTouchOutside(false);

    final Window window = progressDialog.getWindow();
    if (window != null) {
        window.setBackgroundDrawableResource(android.R.color.transparent);
    }else {
        Logger.logError("window == null", new NullPointerException(), context);
    }

    final TextView msg = (TextView) progressDialog.findViewById(R.id.id_tv_loadingmsg);
    msg.setText(text);

    return progressDialog;
}

据我所知，没有什么特别的，只是创建对话框，显示它并最终关闭它，就是这样......

为什么我会收到此错误？

我做错了什么？

AsynkTask

public void setCroppedPreviewImage() {
    new AsyncTask<Void, Void, byte[]>() {
        @Override
        protected void onPreExecute() {
            super.onPreExecute();
            openProgress();
        }

        @Override
        protected byte[] doInBackground(Void... voids) {
            final String path = model.getImageFilePath();
            final Bitmap croppedBitmap = getCroppedBitmapFromPath(path);
            return getByteArrayFromBitmap(croppedBitmap);
        }

        @Override
        protected void onPostExecute(byte[] result) {
            super.onPostExecute(result);
            closeProgress();
            iActivityAcceptNotAccept.setPreviewImage(result);
        }
    }.execute();
}

Answer 1

实际上，在我的例子中，原因不是正在进行的对话框。我试图删除进度并揭开真正的原因。这是由于位图解码过程中的 OOM...但我不知道为什么我收到错误日志，其中在 progressdialog 中说明了这个原因。

最终我的位图太大了，我不得不缩小它

我是这样完成的(如果有人有同样的问题)

final BitmapFactory.Options options = new BitmapFactory.Options();
    options.inSampleSize = 2;
    final Bitmap bitmap = BitmapFactory.decodeFile(photo.getAbsolutePath(), options);

这意味着我将位图大小缩小了 2 倍，现在应用程序可以完美运行!
