一个页面多个TextView跑马灯,与焦点无关

package com.travelsky.bluesky.utils;

import android.content.Context;

public class MarqueeTextView extends TextView
{
    public MarqueeTextView(Context context)
    {
        this(context, null);
    }
    
    public MarqueeTextView(Context context, AttributeSet attrs)
    {
        super(context, attrs);
        
        setFocusable(true);
        setFocusableInTouchMode(true);
        
        setSingleLine();
        setEllipsize(TextUtils.TruncateAt.MARQUEE);
        setMarqueeRepeatLimit(-1);
    }
    
    public MarqueeTextView(Context context, AttributeSet attrs, int defStyle)
    {
        super(context, attrs, defStyle);
        
        setFocusable(true);
        setFocusableInTouchMode(true);
        
        setSingleLine();
        setEllipsize(TextUtils.TruncateAt.MARQUEE);
        setMarqueeRepeatLimit(-1);
    }

    @Override
    protected void onFocusChanged(boolean focused, int direction, Rect previouslyFocusedRect)
    {
        if (focused)
        {
            super.onFocusChanged(focused, direction, previouslyFocusedRect);
        }
    }
    
    @Override
    public void onWindowFocusChanged(boolean focused)
    {
        if (focused)
        {
            super.onWindowFocusChanged(focused);
        }
    }
    
    @Override
    public boolean isFocused()
    {
        return true;
    }
}

因为已经做了焦点等处理,所以不用再配置

android:ellipsize="marquee"
android:focusable="true"
android:focusableInTouchMode="true"
android:gravity="center_vertical"
android:marqueeRepeatLimit="marquee_forever"

直接引用即可
