Java 如何检查startActivityForResult、override onActivityResult方法中按下的按钮？

我有三个按钮（R.id.1、R.id.2、R.id.3）和三个文本视图（a、b、c）。如何检查在ActivityResult上按下的按钮，以便根据按钮设置文本视图

@Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
    switch(requestCode)
    {
        case 0:
           //check which button was pressed
            String b = data.getStringExtra("a");
          //Apply setText(b);
            }
           break;

        case 1:
         //check which button was pressed
            String result1=data.getStringExtra("text");
           // Apply setText(result);
            break;


        case 2:
          // check which button was pressed
            String b2 = data.getStringExtra("a");
           // Apply setText (b2);
            break;

示例：在案例0中，按下了R.id.1，a.setText（b）也会按下。

If R.id.1 was pressed, a.setText()
If R.id.2 was pressed, b.setText()
If R.id.3 was pressed, c.setText()

代码

                Button button1 = (Button) claims.findViewById(R.id.1);
                Button button2 = (Button) claims.findViewById(R.id.2);
                Button button3 = (Button)claims.findViewById(R.id.3);
                a=(TextView)claims.findViewById(R.id.textView1);
                b=(TextView)claims.findViewById(R.id.textView2);
                c=(TextView)claims.findViewById(R.id.textView3);

                button1.setOnClickListener(listener);
                button2.setOnClickListener(listener); 
                button3.setOnClickListener(listener);
                  View.OnClickListener listener = new View.OnClickListener() {
                    public void onClick(View v) {
                        AlertDialogRadio();

                    }
                };


         public void AlertDialogRadio() {
                final CharSequence[] ClaimsModel = {"Sunny", "Raining", "Cloudy"};

                AlertDialog.Builder alt_bld = new AlertDialog.Builder(getActivity());
                alt_bld.setTitle("Select Weather");
                alt_bld.setSingleChoiceItems(ClaimsModel, -1, new DialogInterface
                        .OnClickListener() {
                    public void onClick(DialogInterface dialog, int item) {
                        if (item == 0) {
                            Intent intent = new Intent(getActivity().getApplicationContext(), Sunny.class);
                            startActivityForResult(intent, 0);
                        } else if (item == 1) {
                            Intent intent = new Intent(getActivity().getApplicationContext(), Rainy.class);
                            startActivityForResult(intent, 1);
                        } else if (item == 2) {
                            Intent intent = new Intent(getActivity().getApplicationContext(), Cloudy.class);
                            startActivityForResult(intent, 2);
                         }
     }
                    dialog.dismiss();

                }
            });
            AlertDialog alert = alt_bld.create();
            alert.show();


        }


          @Override
            public void onActivityResult(int requestCode, int resultCode, Intent data) {
            switch(requestCode)
            {
                case 0:
                   //check which button was pressed
                    String b = data.getStringExtra("a");
                  //Apply setText(b);
                    }
                   break;

                case 1:
                 //check which button was pressed
                    String result1=data.getStringExtra("text");
                   // Apply setText(result);
                    break;


                case 2:
                  // check which button was pressed
                    String b2 = data.getStringExtra("a");
                   // Apply setText (b2);
                    break;
    }

您可以使用请求代码进行检查

         View.OnClickListener listener = new View.OnClickListener() {
            public void onClick(View v) {
                AlertDialogRadio(v.getId());

你能解释一下吗？我应该在哪里添加startActivityForResult（intent，requestCode1）；？您应该添加startActivityForResult（intent，requestcode1）；单击相应按钮的函数，但三个按钮具有相同的函数，即调用AlertDialogRadio（）在AlertDialogRadio中添加变量requestCode检查我编辑的代码您可以在onActivityResult中使用开关，如果我在AlertRadioDialog中添加开关（id），则可以删除我使用的其他按钮，最后，编译器如何知道按下了哪个按钮？请注意代码。AlertDialogRadio（v.getId（））；使用视图id，您可以检测单击了哪个按钮，但我应该在onActivityResult？编辑的代码中写入什么内容。您可以使用bundle将任何数据传递给onAvtivityResult

int requestCode1 = 1;
int requestCode2 = 2;
int requestCode3 = 3;

Button b1 =(Button) findViewById(R.id.button1);
Button b2 =(Button) findViewById(R.id.button2);
Button b3 =(Button) findViewById(R.id.button3);

b1.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        AlertDialogRadio(requestCode1)

    }
});
b2.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        AlertDialogRadio(requestCode2)

    }
});
b3.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        AlertDialogRadio(requestCode3)

    }
});



@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if(resultCode == requestCode1){}//button 1
    else if(resultCode == requestCode2){}//button 2
    else if(resultCode == requestCode3){}//button 3
