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>
