Android 设置DrawableRight和DrawableLeft 的通用点击事件

package com.lb.frame.views; import android.annotation.SuppressLint; import android.content.Context; import android.graphics.drawable.Drawable; import android.util.AttributeSet; import android.view.MotionEvent; import android.view.View; import android.widget.EditText; /** * Created by libin on 2016/11/18. */ public class AddAndSubEditText extends EditText { private OnDrawableLeftListener mLeftListener; private OnDrawableRightListener mRightListener; private OnDrawableListener drawableListener; final int DRAWABLE_LEFT = 0; final int DRAWABLE_TOP = 1; final int DRAWABLE_RIGHT = 2; final int DRAWABLE_BOTTOM = 3; @SuppressLint("NewApi") public AddAndSubEditText(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) { super(context, attrs, defStyleAttr, defStyleRes); } public AddAndSubEditText(Context context, AttributeSet attrs, int defStyleAttr) { super(context, attrs, defStyleAttr); } public AddAndSubEditText(Context context, AttributeSet attrs) { super(context, attrs); } public AddAndSubEditText(Context context) { super(context); } public void setOnDrawableLeftListener(OnDrawableLeftListener listener) { this.mLeftListener = listener; } public void setOnDrawableRightListener(OnDrawableRightListener listener) { this.mRightListener = listener; } public void setOnDrawableClickListener(OnDrawableListener listener) { this.drawableListener = listener; } public interface OnDrawableListener { void onDrawableLeftClick(View view); void onDrawableRightClick(View view); } public interface OnDrawableLeftListener { void onDrawableLeftClick(View view); } public interface OnDrawableRightListener { void onDrawableRightClick(View view); } @SuppressLint("ClickableViewAccessibility") @Override public boolean onTouchEvent(MotionEvent event) { switch (event.getAction()) { case MotionEvent.ACTION_UP: if (mRightListener != null) { Drawable drawableRight = getCompoundDrawables()[DRAWABLE_RIGHT]; if (drawableRight != null && event.getRawX() >= (getRight() - drawableRight.getBounds().width())) { mRightListener.onDrawableRightClick(this); return true; } } if (drawableListener != null) { Drawable drawableRight = getCompoundDrawables()[DRAWABLE_RIGHT]; if (drawableRight != null && event.getRawX() >= (getRight() - drawableRight.getBounds().width())) { drawableListener.onDrawableRightClick(this); return true; } Drawable drawableLeft = getCompoundDrawables()[DRAWABLE_LEFT]; if (drawableLeft != null && event.getRawX() <= (getLeft() + drawableLeft.getBounds().width())) { drawableListener.onDrawableLeftClick(this); return true; } } if (mLeftListener != null) { Drawable drawableLeft = getCompoundDrawables()[DRAWABLE_LEFT]; if (drawableLeft != null && event.getRawX() <= (getLeft() + drawableLeft.getBounds().width())) { mLeftListener.onDrawableLeftClick(this); return true; } } break; } return super.onTouchEvent(event); } } 使用方法:同时设置左右两边的图片点击事件,也可单独设置,方便使用 people_num_et.setOnDrawableClickListener(new AddAndSubEditText.OnDrawableListener() { @Override public void onDrawableLeftClick(View view) { if (peopleNum > 1) { people_num_et.setText(String.valueOf(--peopleNum)); } else { T.show("至少1人"); } } @Override public void onDrawableRightClick(View view) { if (peopleNum < 3) { people_num_et.setText(String.valueOf(++peopleNum)); } else { T.show("最多3人"); } } }); people_num_et.setOnDrawableLeftListener(new AddAndSubEditText.OnDrawableLeftListener() { @Override public void onDrawableLeftClick(View view) { if (peopleNum > 0) { people_num_et.setText(--peopleNum); } } }); people_num_et.setOnDrawableRightListener(new AddAndSubEditText.OnDrawableRightListener() { @Override public void onDrawableRightClick(View view) { if (peopleNum < 3) { people_num_et.setText(++peopleNum); } else { T.show("最多3人"); } } });参考:http://blog.csdn.net/lib739449500/article/details/50236439修改
