Android PopWindow 设置背景亮度的实例
设置背景
/** * 设置添加屏幕的背景透明度 * @param bgAlpha */ public void backgroundAlpha(float bgAlpha) {
WindowManager.LayoutParams lp = getWindow().getAttributes();
lp.alpha = bgAlpha;
//0.0-1.0 getWindow().setAttributes(lp);
}
调用代码
recomPopup = new RecomPopup(mContext);
recomPopup.setShowListener(new RecomPopup.ShowListener() {
@Override public void show() {
backgroundAlpha(0.6f);
}
}
);
recomPopup.setDismissListener(new RecomPopup.DismissListener() {
@Override public void dismiss() {
backgroundAlpha(1f);
}
}
);
recomPopup.showAtLocation(include_bottom, Gravity.NO_GRAVITY, 0, DevicesInfoUtils.getScreenHeight(mContext) - recomPopup.getHeight());
PopWindow代码
private ShowListener showListener;
private DismissListener dismissListener;
@Override public void showAtLocation(View parent, int gravity, int x, int y) {
super.showAtLocation(parent, gravity, x, y);
if (showListener != null){
showListener.show();
}
}
@Override public void dismiss() {
super.dismiss();
if (dismissListener != null){
dismissListener.dismiss();
}
}
public void setShowListener(ShowListener showListener) {
this.showListener = showListener;
}
public void setDismissListener(DismissListener dismissListener) {
this.dismissListener = dismissListener;
}
public interface ShowListener{
void show();
}
public interface DismissListener{
void dismiss();
}
