Question

我正在尝试用函数创建程序。

代码非常简单，但我在java中苦苦寻找基本语法。

OnClickListener voiceListener = new OnClickListener() {
          public void onClick(View v) { 
              FA();//I want FB is operated after FA and onActivityResult are finished..
              FB(); 
            }
        };


private void FA(){...startActivityForResult(intent,check);  
        }
private void FB(){}

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if(requestCode == check && resultCode == RESULT_OK){
            results = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
}
        super.onActivityResult(requestCode, resultCode, data);
    }
}

// 问题是，当我点击按钮时，FA和FB一起操作，看起来像FA，FB 我想看到的是，在执行FA（意图通过）后，程序进入onActivityResult并将结果应用于FB。这样做我应该在哪里触摸？我该怎么办？我期待看到意见！：）

在onActivityResult方法中执行FB（）方法的操作，就像这样

OnClickListener voiceListener = new OnClickListener() {
          public void onClick(View v) { 
              FA();//I want FB is operated after FA and onActivityResult are finished..
              //Don't call FB over here
            }
        };

//FA method defined here which startActivityForResult
private void FA(){...startActivityForResult(intent,check);  
        }

//FB method defined here    
private void FB(){}

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if(requestCode == check && resultCode == RESULT_OK){
            results = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
            //Call FB over here
            FB(); 
}
        super.onActivityResult(requestCode, resultCode, data);
    }
}

我希望这会有所帮助。还有疑惑吗？评论如下。
