打开onClick按钮

Question

我有三个按钮

Button1 btn1 = (Button) findViewById(R.id.button1);
Button2 btn2 = (Button) findViewById(R.id.button2);
Button3 btn3 = (Button) findViewById(R.id.button3);

btn1.setOnClickListener(this);
btn2.setOnClickListener(this);
btn3.setOnClickListener(this);

public void onClick(View v) {

switch(v){
 case bt1:
 //SOME CODE
 break;
 case bt2:
 //SOME CODE
 break;
 case bt3:
 //SOME CODE
 break;


}

当它到达开关时它会断开,任何人都可以帮助我吗？第一篇文章希望每个人都好

Answer 1

改变它

    Button1 btn1 = (Button) findViewById(R.id.button1);
Button2 btn2 = (Button) findViewById(R.id.button2);
Button3 btn3 = (Button) findViewById(R.id.button3);

btn1.setOnClickListener(this);
btn2.setOnClickListener(this);
btn3.setOnClickListener(this);

public void onClick(View v) {

switch(v.getId()){
 case R.id.button1:
 //SOME CODE
 break;
 case R.id.button2:
 //SOME CODE
 break;
 case R.id.button3:
 //SOME CODE
 break;


}

Answer 2

     public void onClick(View v) {

     switch(v.getId()){
     case R.id.button1:
     //SOME CODE
     break;
     case R.id.button2:
     //SOME CODE
     break;
     case R.id.button3:
     //SOME CODE
     break;
 }

• 视图传递给onClick
• 因此,切换应查找视图,而不是按钮名称.
