当我尝试执行NDK构建时,我得到以下错误列表...任何人都有任何线索？

我有以下xml:

 <?xml version="1.0" encoding="utf-8"?>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical" >
    <TextView
    android:id="@+id/text_view"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_gravity="center_horizontal|center_vertical"
    android:layout_marginTop="20dip"
    android:text="Fragment1"
    android:textAppearance="?android:attr/textAppearanceLarge"
    android:textSize="30dip" />

    <Button 
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Button1"/>


 <GridView 
      android:id="@+id/gridview"
      android:layout_width="wrap_content" 
      android:layout_height="match_parent"overla
      android:columnWidth="90dp"
      android:numColumns="auto_fit"
      android:verticalSpacing="10dp"
      android:horizontalSpacing="10dp"
      android:stretchMode="columnWidth"
      android:gravity="center"/>                            

        <Button 
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Button1"/>
 </LinearLayout>

button1用于切换网格视图的可见性.但是,当网格视图不可见时,按钮不会填满屏幕.他们占据了屏幕的一半.当网格视图可见时,按钮占据了我想要的所有屏幕.我无法理解这种奇怪的行为.

我有一个AlertDialog可以取消(通过后退按钮或在对话框外单击).如果对话框被取消,我需要撤消一些更改,所以我需要控制它何时被取消.

我试图创建自己的子类AlertDialog来覆盖一些函数(我想我应该覆盖onContextMenuClosed,我想做一些测试来找到正确的函数).

我创建了自己的Builder扩展AlertDialog.Builder来创建我的对话框,我想要覆盖该create()函数.我检查了AlertDialog.Builder->create()代码,它使用变量AlertController.AlertParamsP来获取一些所需的数据,但是该变量是私有的,我无法从我的构建器访问它,因此我无法创建对话框.

如何AlertDialog取消是否可以控制？使用setCancellable(false)不是一个选项,我希望用户能够取消它.

谢谢!

我动态创建了很多按钮.如何在两个按钮之间添加空格.请帮我.提前致谢

我的代码:

private LinearLayout LLDynamic;

 private RelativeLayout.LayoutParams ParaOne;

ParaOne = new RelativeLayout.LayoutParams(280, 30);

Button button1= new Button(Twindo_fromEditGroup.this);
button1.setTextSize(16);


LLDynamic = new LinearLayout(Twindo_fromEditGroup.this); 
LLDynamic.setOrientation(LinearLayout.VERTICAL);
LLDynamic.addView(button1,ParaOne);

为了创建磁贴管理系统,我在res/drawable目录中有一包图像.如何动态加载该资源？

有像getDrawable(String)这样的函数吗？
