安卓自定义界面——textview显示带小红点

这个自定义view是从我原有的项目中提取出来的。

可是因为突然有一栏要隐藏，导致我的小红点显示很难看，直接跑到字上面去了，于是我决定自定义一个view，来满足需求

代码如下：

textview_withpoint.xml

<?xml version="1.0" encoding="utf-8"?><RelativeLayout    xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent"    android:layout_height="wrap_content">   <TextView       android:id="@+id/tv_content"       android:layout_width="match_parent"       android:layout_height="wrap_content"       android:gravity="center"       android:paddingBottom="@dimen/space_10"       android:paddingTop="@dimen/space_10"       />    <TextView        android:id="@+id/tv_notice"        android:layout_width="@dimen/space_08"        android:layout_height="@dimen/space_08"        android:background="@mipmap/sy_new_xx"        android:layout_alignParentRight="true"        android:layout_marginRight="@dimen/space_05"        android:layout_marginTop="@dimen/space_05"        android:visibility="invisible"        /></RelativeLayout>

import android.content.Context;import android.content.res.ColorStateList;import android.support.annotation.ColorInt;import android.util.AttributeSet;import android.view.LayoutInflater;import android.view.View;import android.widget.RelativeLayout;import android.widget.TextView;/** * Created by dawn on 2017/11/21. *  QQ:272398235 * 功能动态实现textview边上的小红点 */public class TextViewWithPoint extends RelativeLayout{    private TextView tv_content,tv_notice;    private Context context;    public TextViewWithPoint(Context context) {        super(context);        this.context=context;        setupView();    }    public TextViewWithPoint(Context context, AttributeSet attrs) {        super(context, attrs);        this.context=context;        setupView();    }    private void setupView() {        LayoutInflater inflater = (LayoutInflater) context                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);        inflater.inflate(R.layout.textview_withpoint, this);        tv_content= (TextView) findViewById(R.id.tv_content);        tv_notice= (TextView) findViewById(R.id.tv_notice);    }    public void setText(String msg){        tv_content.setText(msg);    }    public void setTextColor(@ColorInt int color) {        tv_content.setTextColor(color);    }    /**     * @param bol  true==显示红点     *             false==不显示红点     */    public void setRedPoint(boolean bol){        if(bol){            tv_notice.setVisibility(VISIBLE);        }else{            tv_notice.setVisibility(INVISIBLE);        }    }}

使用方法就省略了
