如何让popupwindow 显示在整个屏幕的中央

Answer 1

调用显示的时候用showAtLocation，然后第二个参数选择Gravity.center，第三个第四个写0，就可以居中了

Answer 2

popupwindow 显示在屏幕中央的办法
public static void showShareWindow(Activity activity, View parentView, String pageName){ View mContentView = null; V5ShareView mShareView = null; if(mContentView == null){ mContentView = LayoutInflater.from(activity).inflate(R.layout.v5_share_layout, null); } if(mPopUpWindow == null){ mPopUpWindow = new PopupWindow(mContentView, LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT); mPopUpWindow.setBackgroundDrawable(new BitmapDrawable()); mPopUpWindow.setOutsideTouchable(true); mPopUpWindow.setFocusable(true); } if(mShareView == null){ mShareView = new V5ShareView(mContentView,pageName,activity); } mShareView.setOnShareViewDismiss(new ShareViewDismiss() { @Override public void dismiss() { mPopUpWindow.dismiss(); } }); mPopUpWindow.showAtLocation(activity.getWindow().getDecorView(), Gravity.CENTER, 0, 0);}

Answer 3

通过设置Dialog的样式实现

public static void showShareWindow(Activity activity, View parentView, String pageName){
View mContentView = null;
V5ShareView mShareView = null;
if(mContentView == null){
mContentView = LayoutInflater.from(activity).inflate(R.layout.v5_share_layout, null);
}
if(mPopUpWindow == null){
mPopUpWindow = new PopupWindow(mContentView, LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT);
mPopUpWindow.setBackgroundDrawable(new BitmapDrawable());
mPopUpWindow.setOutsideTouchable(true);
mPopUpWindow.setFocusable(true);
}
if(mShareView == null){
mShareView = new V5ShareView(mContentView,pageName,activity);
}
mShareView.setOnShareViewDismiss(new ShareViewDismiss() {
@Override
public void dismiss() {
mPopUpWindow.dismiss();
}
});
mPopUpWindow.showAtLocation(activity.getWindow().getDecorView(), Gravity.CENTER, 0, 0);
}
