Question

我在textviews中有三个Activity并且要识别哪个textview被按下我正在使用下面的方法并相应地设置微调器的值，但是活动无法识别此方法。我尝试了很多方法，但没有弄错。需要帮忙当我点击textview应用程序崩溃并且日志显示此错误

java.lang.IllegalStateException：找不到方法 onClick_leave（View）在父或祖先的上下文中 android：在视图类上定义的onClick属性 android.support.v7.widget.AppCompatTextView，id为'pl'

这是我的代码：

public void onClick_leave(View v) {
        if (v.getId() == R.id.cl) {
            Intent intent = new Intent(getActivity(), ApplyLeave.class);
            int leave = 0;
            intent.putExtra("leave", leave);
            startActivity(intent);


        } else if (v.getId() == R.id.pl) {
            Intent intent = new Intent(getActivity(), ApplyLeave.class);
            int leave = 1;
            intent.putExtra("leave", leave);
            startActivity(intent);


        } else if (v.getId() == R.id.sl) {
            Intent intent = new Intent(getActivity(), ApplyLeave.class);
            int leave = 2;
            intent.putExtra("leave", leave);

            startActivity(intent);
        } else if (v.getId() == R.id.edit_menu) {
            Intent intent = new Intent(getActivity(), ApplyLeave.class);
            startActivity(intent);

        }
    }

Answer 1

您应该使用setOnClickListener。

注册单击此视图时要调用的回调。如果这视图不可点击，它变得可点击。

       firstButtonOBJ = (Button) findViewById(R.id.buttonOne); //Global
       firstButtonOBJ.setOnClickListener(this);
       secondButtonOBJ = (Button) findViewById(R.id.buttonTwo);
       secondButtonOBJ.setOnClickListener(this);


    // onClick is called when a view has been clicked.
    @Override
    public void onClick(View v) 
    { 
    // Parameter v stands for the view that was clicked.  

        // getId() returns this view's identifier.
        if(v.getId() == R.id.buttonOne)
        {
            // Your Work
        }
        else if(v.getId() == R.id.buttonTwo)
        {
            // Your Work
        }
    }
