AndroidTextView跑马灯+悬浮窗口

首先自定义TextView

public class MarqueeText extends TextView{public MarqueeText(Context con) {  super(con);}public MarqueeText(Context context, AttributeSet attrs) {  super(context, attrs);}public MarqueeText(Context context, AttributeSet attrs, int defStyle) {  super(context, attrs, defStyle);}@Overridepublic boolean isFocused() {return true;}@Overrideprotected void onFocusChanged(boolean focused, int direction,   Rect previouslyFocusedRect) {  }}

在XML布局中TextView

  android:id="@+id/TextView"

            android:layout_
            android:layout_
            android:layout_gravity="center_vertical"

            android:textColor="@android:color/white"
        android:textSize="22dp"        
        android:ellipsize="marquee" 
        android:focusable="true" 
        android:singleLine="true"
        android:marqueeRepeatLimit="marquee_forever" 
        android:focusableInTouchMode="true" 
        android:scrollHorizOntally="true"

mqt=(MarqueeText) floatView.findViewById(R.id.TextView);
 mqt.setMovementMethod(ScrollingMovementMethod.getInstance()); // Android开发网提示相关的可以查看
mqt .setMarqueeRepeatLimit(6);

private void createFloatView() {
mWindowManager = (WindowManager) getApplication().getSystemService(Context.WINDOW_SERVICE);
sW = mWindowManager.getDefaultDisplay().getWidth();
sH = mWindowManager.getDefaultDisplay().getHeight();
initWindowParams();
LayoutInflater inflater = LayoutInflater.from(getApplicationContext());
floatView = inflater.inflate(R.layout.bo_view, null);
mqt=(MarqueeText) floatView.findViewById(R.id.TextView);
 mqt.setMovementMethod(ScrollingMovementMethod.getInstance()); // Android开发网提示相关的可以查看
mqt .setMarqueeRepeatLimit(6);
mWindowManager.addView(floatView, wmParams);

}

private void initWindowParams() {
wmParams = new LayoutParams();
wmParams.type = LayoutParams.TYPE_SYSTEM_ALERT;
wmParams.format = PixelFormat.RGBA_8888;
wmParams.flags = LayoutParams.FLAG_NOT_FOCUSABLE;
wmParams.gravity = Gravity.LEFT | Gravity.BOTTOM;
wmParams.x = 0;
wmParams.y = 0;
wmParams.width = WindowManager.LayoutParams.FILL_PARENT;
wmParams.height =  60;
eatParams = new LayoutParams();
eatParams.type = LayoutParams.TYPE_SYSTEM_ALERT;
eatParams.format = PixelFormat.RGBA_8888;
eatParams.flags = LayoutParams.FLAG_NOT_FOCUSABLE;
eatParams.gravity = Gravity.LEFT | Gravity.BOTTOM;
eatParams.x = 0;
eatParams.y = sH / 2 - 150;
eatParams.width = WindowManager.LayoutParams.FILL_PARENT;
eatParams.height = WindowManager.LayoutParams.WRAP_CONTENT;  ;
}
