界面布局自定义Layout, 边框shape文件， 按钮selector文件及用法

package com.lonshin.chexiaodi.utils;

import android.content.Context;
import android.util.AttributeSet;
import android.util.Log;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnTouchListener;
import android.widget.RelativeLayout;

import com.krislq.sliding.R;

public class ClickableCornerLayout extends RelativeLayout implements OnTouchListener  {
    
    public ClickableCornerLayout(Context context) {
        super(context);
    }

    public ClickableCornerLayout(Context context, AttributeSet attrs) {
        super(context, attrs);
        this.setBackgroundResource(R.drawable.table_style);//这里也可以set成ARGB颜色
        setOnTouchListener(this);
        setClickable(true);
        
    }
    
    public ClickableCornerLayout(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        this.setBackgroundResource(R.drawable.table_style);
        setOnTouchListener(this);
        setClickable(true);
    }

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        if (event.getAction() == MotionEvent.ACTION_DOWN) {
            this.setBackgroundResource(R.drawable.table_style_dedede);
        } else if (event.getAction() == MotionEvent.ACTION_UP) {
            this.setBackgroundResource(R.drawable.table_style);
        }
        return false;
    }
}

可如上自定义一个Layout.

想让一个widget圆角等，可定义一个shape文件，然后再设置background="@drawable/xxxxxx"

shape文件需要以下几个内容：

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <corners android:radius="6.0dp"/>
    <solid android:color="#ffffff"/>
    <stroke
        android:width="1dp"
        android:color="#cccccc"/>
</shape>

按钮需要selector文件，同样需要backround="@drawable/xxxx"

<?xml version="1.0" encoding="UTF-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
     <item android:state_pressed="true"
           android:drawable="@drawable/btn_call_s_hit" /> <!-- pressed -->
     <item android:state_focused="true"
           android:drawable="@drawable/btn_call_s" /> <!-- focused -->
     <item android:drawable="@drawable/btn_call_s" /> <!-- default -->
 </selector>
