Android基于TextView不获取焦点实现跑马灯效果-创新互联

本文实例讲述了Android基于TextView不获取焦点实现跑马灯效果。分享给大家供大家参考，具体如下：

1. 写一个类继承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;
  }
}
