我有三个按钮（R.id.1，R.id.2，R.id.3）和三个textView（a，b，c）。如何检查按下了哪个按钮onActivityResult，以便TextView可以相应地设置为按钮？
@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，因此将是a.setText（b）....
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;
}

您可以查看“请求代码”。
View.OnClickListener listener = new View.OnClickListener() {
public void onClick(View v) {
AlertDialogRadio(v.getId());
}
};
public void AlertDialogRadio(int id) {
final CharSequence[] ClaimsModel = {"Sunny", "Raining", "Cloudy"};
switch(id){
case R.id.1:
break;
case R.id.2:
break;
case R.id.3:
break;
}
