该自定义view内部已经处理外部点的击事件兼容，直接可以在外部设置点击事件，代码可以去仓库https://github.com/wangsen927/MoveImageView，也可以参考以下代码：
/**
* 如果view随手指拖动时，同时需要点击事件，直接在外部设置即可，内部已解决冲突

}在布局文件中引用后，直接可用，如：
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.moveimageview.MainActivity">
<com.moveimageview.MoveImageView
android:id="@+id/iv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@mipmap/ic_launcher"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</android.support.constraint.ConstraintLayout>public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
findViewById(R.id.iv).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(final View v) {
Toast.makeText(MainActivity.this,"onClickonClick",Toast.LENGTH_SHORT).show();
}
});
}
}效果如下：
