Question

我是新来的，所以我想询问上面的标题，

我有这样的代码：

public class TanyaDokter extends Fragment {

View View;
public TanyaDokter(){}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    final View view = inflater.inflate(R.layout.activity_tanya_dokter, container, false);


    Button button = (Button)view.findViewById(R.id.button1);
    button.setOnClickListener(new OnClickListener()

    {   
        public void onClick(View v){
            switch(v.getId()){

            case R.id.button1:
            Intent intent1 = new Intent(view.getContext(), FormTanyaDokter.class);
                startActivity(intent1);
                break;

这段代码是成功点击一个按钮，但我想制作两个或更多按钮，所以我的问题是如何使这个代码可以处理两个或多个按钮点击。感谢

Answer 1

首先在xml文件中创建按钮：然后：有两种方法：

首先：

Button button = (Button)view.findViewById(R.id.button1);
Button button2 = (Button)view.findViewById(R.id.button2);
Button button3 = (Button)view.findViewById(R.id.button3);
button.setOnClickListener(this);
button2.setOnClickListener(this);
button3.setOnClickListener(this);
 ----
}       

public void onClick(View v){
    switch(v.getId()){

    case R.id.button1:
        Intent intent1 = new Intent(view.getContext(), FormTanyaDokter.class);
        startActivity(intent1);
        break;

    case R.id.button2:
        //your action
        break;
    case R.id.button3:
        //your action
        break;
    }
}

第二

Button button = (Button)view.findViewById(R.id.button1);
Button button2 = (Button)view.findViewById(R.id.button2);
Button button3 = (Button)view.findViewById(R.id.button3);

button.setOnClickListener(new OnClickListener() {   

    public void onClick(View v){

        Intent intent1 = new Intent(view.getContext(), FormTanyaDokter.class);
        startActivity(intent1);

    }};

button2.setOnClickListener(new OnClickListener() {   

    public void onClick(View v) {
    }

});

button3.setOnClickListener(new OnClickListener() {   

    public void onClick(View v){
    }

});

Answer 2

为了处理多个按钮点击事件，您必须这样做，

    public void onClick(View v){
        switch(v.getId()){

        case R.id.button1:
        Intent intent1 = new Intent(view.getContext(), FormTanyaDokter.class);
            startActivity(intent1);
            break;

       case R.id.button2:
       //your action
            break;
   }
 }

单按钮

     Button cancel  = (Button) view.findViewById(R.id.button1);
     cancel.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                       // your logic here....
                    }
                });

用于多个按钮。

  Button cancel1  = (Button) view.findViewById(R.id.button1);
  Button cancel2  = (Button) view.findViewById(R.id.button2);
  Button cancel3  = (Button) view.findViewById(R.id.button3);
  cancel1 .setOnClickListener(this);
  cancel2 .setOnClickListener(this);
  cancel2 .setOnClickListener(this);

OnClicked handle here

 @Override
  public void onClick(View v){
            switch(v.getId()){

            case R.id.button1:
            Intent intent1 = new Intent(view.getContext(), FormTanyaDokter.class);
                startActivity(intent1);
                break;
 case R.id.button2:
            Intent intent1 = new Intent(view.getContext(), FormTanyaDokter.class);
                startActivity(intent1);
                break;
 case R.id.button3:
            Intent intent1 = new Intent(view.getContext(), FormTanyaDokter.class);
                startActivity(intent1);
                break;

    }
 }

Answer 4

您可以向xml布局添加更多按钮，然后通过此

处理所有点击

 Button button = (Button)view.findViewById(R.id.button1);
    Button button2 = (Button)view.findViewById(R.id.button2);
    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent1 = new Intent(view.getContext(), FormTanyaDokter.class);
            startActivity(intent1);
        }
    });

    button2.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent1 = new Intent(view.getContext(), SecondActivity.class);
            startActivity(intent1);
        }
    });

Answer 5

您还可以将onClickListener设置为变量，并将所有按钮设置为该变量。例如

View.onClickListener listener = new onClickListener()
{
    void onClick...
};
button1.setOnClickListener(listener);
button2.setOnClickListener(listener);
button3.setOnClickListener(listener);
