Android TextView Horizontal scrolling (marquee effect)

Android TextView When the text is a long time to expect it to scroll horizontally, the following is a pro-test feasible method.

：

1. Custom TextView, override the IsFocused () method to return True to have the custom TextView always in the get focus state.

Package Com.example.shen.marqueedemo;import Android.content.context;import Android.util.attributeset;import android.widget.textview;/** * Created by Shen on 2015/8/19. */public class Marqueetextview extends TextView {public    Marqueetextview (context context) {        super (context);    } Public    Marqueetextview (context context, AttributeSet Attrs) {        Super (context, attrs);    }    Public Marqueetextview (context context, AttributeSet attrs, int defstyleattr) {        Super (context, attrs, defstyleattr) ;    }    @Override Public    Boolean isFocused () {        return true;    }}

2. Layout files

Android:sigleline= "true"//single line

Android:ellipsize= "marquee"//display in the way of a marquee (animation lateral movement)

android:marqueerepeatlimit= "Marquee_forever"//Keep rolling

<relativelayout xmlns:android= "http://schemas.android.com/apk/res/android"    android:layout_width= "Match_ Parent "    android:layout_height=" match_parent ">    <com.example.shen.marqueedemo.marqueetextview        Android:layout_width= "200DP"        android:layout_height= "wrap_content"        android:text= "hello_world! hello_ world! hello_world! "        android:layout_centerinparent=" true "        android:ellipsize=" marquee "        android:singleline=" true "        android:marqueerepeatlimit= "Marquee_forever"/></relativelayout>
