在 Android 的 EditText 中单击 drawableleft 的侦听器?

Click listener for drawableleft in EditText in Android?(在 Android 的 EditText 中单击 drawableleft 的侦听器?)

问题描述

是否可以在设计器中声明为 drawableleft

Is it possible to add a OnClickListener to on a drawable that is declared in designer as drawableleft

android:drawableLeft="@drawable/ic_password"

或者有什么方法可以在 EditText

Or is there any way to add a ImageView on the left side of that EditText

推荐答案

对于drawableleft点击监听器:

 editText.setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        final int DRAWABLE_LEFT = 0;
        final int DRAWABLE_TOP = 1;
        final int DRAWABLE_RIGHT = 2;
        final int DRAWABLE_BOTTOM = 3;

       if(event.getRawX() <= (editText.getCompoundDrawables()[DRAWABLE_LEFT].getBounds().width()))
        {
              // your action here
             return true;
        }
        return false;
    }
});

如果您想要 drawable right 的点击监听器，请使用以下条件

In case if you want click listener for drawable right use following condition

if(event.getAction() == MotionEvent.ACTION_UP) {
            if(event.getRawX() >= (editComment.getRight() - editComment.getCompoundDrawables()[DRAWABLE_RIGHT].getBounds().width()))
