android设置window背景颜色,Android WindowManager 背景暗化

主要代码

WindowManager.LayoutParams.FLAG_DIM_BEHIND

mParams.dimAmount = 0.5f;

示例

mWM = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);

mLayoutParams = new LayoutParams();

mLayoutParams.height = LayoutParams.WRAP_CONTENT;

mLayoutParams.width = LayoutParams.MATCH_PARENT;

mLayoutParams.gravity = Gravity.BOTTOM;

mLayoutParams.flags = LayoutParams.FLAG_NOT_TOUCH_MODAL | LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH | LayoutParams.FLAG_DIM_BEHIND;

mLayoutParams.dimAmount = 0.5f;

mLayoutParams.format = PixelFormat.TRANSLUCENT;

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {

mLayoutParams.type = LayoutParams.TYPE_TOAST;

Log.d(TAG, "initWindowManager: TYPE_TOAST");

} else {

mLayoutParams.type = LayoutParams.TYPE_PRIORITY_PHONE;

Log.d(TAG, "initWindowManager: TYPE_PRIORITY_PHONE");

}

mLayoutParams.setTitle("BaseFloatWindowView");

mLayoutParams.windowAnimations = R.style.anim_MarkPhoneNumWindowView;

设置了Flag为LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH后监听addView中的View的触摸事件

@Override

public boolean onTouch(View v, MotionEvent event) {

switch (event.getAction()) {

case MotionEvent.ACTION_OUTSIDE:

//相应逻辑

hide();

return true;

}

return false;

}
