Question

Android 怎么使一个AlertDialog在屏幕的左下角？

Builder a = new AlertDialog.Builder(this);
a.setItems(ShouXuanXiang,new OnClickListener(){
@Override
public void onClick(DialogInterface dialog, int which) {

}});
a.setNegativeButton("返回",null);
AlertDialog aa = a.create();
aa.show();
Window w = aa.getWindow();
w.setGravity(Gravity.BOTTOM);
WindowManager.LayoutParams ww = w.getAttributes();
ww.width=300;
aa.getWindow().setAttributes(ww);

这样做只能让其在上 或下 怎么让它在左下角？（去除和屏幕的间距）

Answer 1

w.setGravity(Gravity.BOTTOM | Gravity.Left);
