1、新建MarqueeTextView 继承自 TextView

import android.content.Context;import android.util.AttributeSet;import android.widget.TextView;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、主布局文件xml代码

    <com.leadingsoft.mbh.marqueetextview.MarqueeTextView        android:id="@+id/tv1"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:ellipsize="marquee"        android:focusable="true"        android:focusableInTouchMode="true"        android:singleLine="true"        android:marqueeRepeatLimit="1"        android:scrollHorizontally="true"        android:text="@string/tv1" />    <com.leadingsoft.mbh.marqueetextview.MarqueeTextView        android:id="@+id/tv2"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:ellipsize="marquee"        android:focusable="true"        android:focusableInTouchMode="true"        android:singleLine="true"        android:text="@string/tv2" />
