android - 警报对话框显示非常缓慢

Question

我正在使用警报对话框来显示自定义 View ，但是警报对话框出现得非常慢。显示大约需要 10 或 15 秒。这是我的代码有什么问题。

LayoutInflater layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            View vDialog = layoutInflater.inflate(R.layout.dialog, null);
            AlertDialog.Builder builder = new AlertDialog.Builder(context);
            builder.setView(vDialog);
                AlertDialog ad = builder.create();
            ad.show();

这是我的 dialog.xml

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout  xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="match_parent"
 android:layout_height ="match_parent" >

<CalendarView
     android:layout_width="50dp"
     android:layout_height ="50dp">        
</CalendarView>

 </FrameLayout>

Answer 1

试试这段代码:

final Dialog dialog = new Dialog(context,
    android.R.style.Theme_Translucent_NoTitleBar);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.dialog);
WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
lp.copyFrom(dialog.getWindow().getAttributes());
lp.width = WindowManager.LayoutParams.MATCH_PARENT;
lp.height = WindowManager.LayoutParams.WRAP_CONTENT;
lp.gravity = Gravity.CENTER;

dialog.getWindow().setAttributes(lp);

dialog.show();
