布局文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="match_parent">

<FrameLayout

android:layout_centerVertical="true"
android:layout_marginBottom="2dip"

android:layout_marginRight="20dip"
android:layout_marginTop="3dip"
android:src="@drawable/iwind_update_notice"
android:visibility="invisible" />
</FrameLayout>
</LinearLayout>

values文件夹下新建attr文件

<?xml version="1.0" encoding="utf-8"?>
<resources>
<declare-styleable name="searchEditTextStyleable">
<attr name="btnBackground" format="reference" />
<attr name="btnText" format="reference|string" />
<attr name="btnTextcolor" format="reference|color" />
<attr name="btnTextsize" format="dimension"/>
<attr name="btnVisibility" format="string"/>
</declare-styleable>
<declare-styleable name="IWindTopBgView" >
<attr name="borderRectColor" format="reference|color"/>
</declare-styleable>
</resources>

自定义控件

public class IWindTopBgView extends TextView {
private int mBorderColor = Color.TRANSPARENT;
private Paint mPaint;
public IWindTopBgView(Context context) {
this(context,Color.TRANSPARENT);
}
public IWindTopBgView(Context context, int color) {
super(context);
mBorderColor = color;
init(context);
}

public IWindTopBgView(Context context, AttributeSet attrs) {
super(context, attrs);
final TypedArray attributes = context.getTheme().obtainStyledAttributes(attrs, R.styleable.IWindTopBgView, 0, 0);
mBorderColor = attributes.getColor(R.styleable.IWindTopBgView_borderRectColor, Color.TRANSPARENT);
init(context);
}

public void setBorderColor(int color){
mPaint.setColor(mBorderColor);
}

private void init(Context context) {
mPaint = new Paint();
mPaint.setAntiAlias(true);
mPaint.setColor(mBorderColor);
mPaint.setStyle(Paint.Style.STROKE);
}

@Override
public void draw(Canvas canvas) {
super.draw(canvas);
//绘制矩形框
canvas.drawRect(0,0,getWidth(),getHeight(),mPaint);
}
}
