按下按钮后的开关状态

Question

So I push either button1, button2, button3, or button4. Pushing any of these Buttons calls method buttonPressed(View v). I want to use a different case depending on the button pressed. For example:

public void buttonPressed(View v){
switch(v){
case button1:
//do something
case button2:
//do something
case button3:
//do something
case button4:
//do something
}}

Obviously, this does not work. I cannot use a switch statement with a View. What is the easiest and most efficient solution to this problem? Thanks!!

Note: I am using android:onClick="buttonPressed" in my .xml

Answer 1

You need to switch on the View's ID, not the View itself

public void buttonPressed(View v){
    switch(v.getId()) {
    case R.id.ButtonOneID:
        //do something
        break;
    case R.id.ButtonTwoID:
        //do something
        break;
    case R.id.ButtonThreeID:
        //do something
        break;
    case R.id.ButtonFourID:
        //do something
        break;
    }
}

Answer 2

public void buttonPressed(View v){
    int id = v.getId();
    switch(id){
    case button1.getId();
        //do something
        break;
    case button2.getId();
        //do something
        break;
    case button3.getId();
        //do something
        break;
    case button4.getId();
        //do something
        break;
    }
}
