我有一个从View扩展的课程
public class SideLightView extends View {
...
...
...
@Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
width = getWidth();
height = getHeight();
if (GlobalValues.DEBUG_MODE) Log.e(TAG, "Screen Width : " + width + "
Height : " + height);
paint.setAntiAlias(true);
paint.setStyle(Paint.Style.STROKE);
paint.setStrokeWidth(strokeWidth);
// paint.setColor(color);
path.moveTo(0, 0);
path.lineTo(0, height);
path.lineTo(width, height);
path.lineTo(width, 0);
path.lineTo(0, 0);
paint.setShader(new LinearGradient(0, 0, 0, height, top_color,
bottom_color, Shader.TileMode.CLAMP));
canvas.drawPath(path, paint);
}
@Override
public boolean onTouchEvent(MotionEvent event) {
// super.onTouchEvent(event);
return false;
}
@Override
public boolean dispatchTouchEvent(MotionEvent event) {
// super.dispatchTouchEvent(event);
return false;
}
}
我正在使用如下所示的Window Manager在服务类中添加此视图:
mWindowManager = (WindowManager) mContext.getSystemService(WINDOW_SERVICE);
int LAYOUT_FLAG;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
LAYOUT_FLAG = WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY;
// for solving error window type 2006
} else {
LAYOUT_FLAG = WindowManager.LayoutParams.TYPE_PHONE; // for solving
error window type 2038
}
WindowManager.LayoutParams params = new WindowManager.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.MATCH_PARENT,
LAYOUT_FLAG,
WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED
// | WindowManager.LayoutParams.FLAG_FULLSCREEN
| WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON
| WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL
| WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE
| WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD
| WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH,
PixelFormat.TRANSPARENT);
params.gravity = Gravity.LEFT;
sideLightView = new SideLightView(mContext);
sideLightView.setClickable(false);
sideLightView.setFocusable(false);
mWindowManager.addView(sideLightView, params);
Animation fade_in_out_animation = AnimationUtils.loadAnimation(mContext,
R.anim.fade_in_and_out);
fade_in_out_animation.setDuration(800);
sideLightView.setStrokeWidth(40);
sideLightView.startAnimation(fade_in_out_animation);
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
@Override
public void run() {
removeView();
}
}, utility.getSideLigthDuration() * 1000); //adding 3 sec delay
我的目的是在锁定屏幕上显示此视图,以供用户在其他应用程序上显示所需的秒数,但由于它在屏幕周围只有一个笔触大小的矩形框,而在中心部分完全没有其他内容,因此保持空白或透明,可以正确显示,但也会消耗我的触摸事件。
每当该视图显示在屏幕上时,它都会消耗触摸事件,用户会感觉手机挂了几秒钟。
我想为此视图禁用触摸监听,最重要的是,将所有触摸事件传递给下面的屏幕,就像用户在此视图出现时通常使用的屏幕一样
我尝试了什么:
如果有人能弄清楚这种情况。 预先感谢。

您可以尝试先为父级布局设置void convert_to_camel(char* phrase){
int j =0;
for(int i=0;i<full_len-1;i++){
if(isalphanum(phrase[i])){
phrase[j] = phrase[i];
j++;
length++;
}
}
int flag = 0;
char new[50];
for (int i=0;i<length;i++){
if(phrase[i]== '95'){
flag = 1;
}
if(flag ==1){
new[i] = toUpper(phrase[i+1]);
i++;
new[i] = phrase[i+1];
flag = 0;
}
else{
new[i] = phrase[i];
}
}
和focusable= "false"
。
现在,在子视图上实现OnTouchListener,并且在接收到Touch Event时从子视图返回true。
enabled="false

WindowManager.LayoutParams params = new WindowManager.LayoutParams(
WindowManager.LayoutParams.MATCH_PARENT,
WindowManager.LayoutParams.MATCH_PARENT,
WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY,
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE |
WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE,
PixelFormat.TRANSPARENT);
添加WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE标志应该可以解决您的问题。
