Question

我正在尝试让我的活动关闭并返回结果，我在父活动中确实有onActivityResult，并且我在其他有效的地方使用了接近相同的方法。

public void deleteFile(){
        boolean deleted=FileManager.getInstance().deleteMeasurementData(this.getIntent().getData(), this);
        if(deleted){
            Toast.makeText(this, originalData.getName() +".mmd Has been deleted", Toast.LENGTH_SHORT);
            setResult(EditMeasurement.RESULT_YES_DELETED);
            finishActivity(EditMeasurement.RESULT_YES_DELETED);
        }else {
            Toast.makeText(this, originalData.getName() +".mmd did NOT delete", Toast.LENGTH_SHORT);
            Log.e(TAG, "File did NOT delete error");
        }

    }

从此菜单调用此方法：

public boolean onOptionsItemSelected(MenuItem item) {
        // Handle item selection
        Log.i(TAG, "something choosen "+item.getItemId()+" it should have been: "+R.id.om_measurement_menu_delete);

        switch (item.getItemId()) {
        case R.id.om_measurement_menu_edit:
            editFile();
            return true;
        case R.id.om_measurement_menu_delete:
            deleteFile();
            return true;
        case R.id.om_measurement_menu_cancel:
            endActivity();
            return true;
        default:
            return super.onOptionsItemSelected(item);
        }
    }

任何有明智想法的人为什么不关闭？

Answer 1

finishActivity用于关闭当前的另一项活动 - http://developer.android.com/reference/android/app/Activity.html#finishActivity(int)，因此只需将其更改为finish();

Answer 2

我把它作为finish（）即使返回但它也不会关闭，然后我意识到那个特定的Activity需要在Manifest中android:launchMode="singleTask"

Finishactivity没有完成活动？
