本文實例講述了Android基于TextView不獲取焦點實現跑馬燈效果。分享給大家供大家參考，具體如下：
1. 寫一個類繼承TextView
package com.example.tt;import android.content.Context;import android.graphics.Rect;import android.util.AttributeSet;import android.widget.TextView;public class ScrollingTextView extends TextView { public ScrollingTextView(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); } public ScrollingTextView(Context context, AttributeSet attrs) { super(context, attrs); } public ScrollingTextView(Context context) { super(context); } @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; }}2. xml 中增加屬性
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" ><com.example.tt.ScrollingTextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="80dip" android:layout_marginBottom="25dip" android:textSize="25sp" android:singleLine="true" android:textColor="@android:color/black" android:ellipsize="marquee" android:focusable="true" android:marqueeRepeatLimit="marquee_forever" android:focusableInTouchMode="true" android:scrollHorizontally="true" android:text="這才是真正的文字跑馬燈效果,文字移動速度，文字移動方向，文字移動的樣式，動畫等等……" android:background="#2FFFFFFF" /><Button android:id="@+id/button1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Button" /></LinearLayout>
3. 在activity中聲明
package com.example.tt;import android.os.Bundle;import android.app.Activity;import android.view.Menu;public class MainActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); }}希望本文所述對大家Android程序設計有所幫助。
