Finishactivity 未完成活动？

Question

我试图让我的活动关闭并返回结果，我的父活动中确实有 onActivityResult ，并且我在其他有效的地方使用了与下面相同的方法。

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");
        }

    }

此方法是从此菜单调用的：

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);
        }
    }

任何人有任何好主意为什么它不关闭吗？

Answer 1

finishActivity 用于关闭当前的另一个 Activity - http ://developer.android.com/reference/android/app/Activity.html#finishActivity(int)，所以只需将其更改为 finish();

Answer 2

我将其设置为 finish()，即使有返回，但它不会关闭，然后我意识到该特定 Activity 需要清单中的 android:launchMode="singleTask"
