小编And*_*ebe的帖子

我刚刚安装了Android Studio,一切运行正常,但是在我的计算机关闭后我第二次打开了AS,我收到以下错误:

"URI is not Registered"

在以下代码行中:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

这只是清单,但它在所有带有该链接的XML文件上发生.我搜索过Stack并没有找到解决我问题的方法.

我正在尝试让我的导航抽屉进入状态栏.我已经阅读了很多关于ScrimInsetsFrameLayout视图的内容,我尝试实现它,但由于某种原因它不会被删除.

这是我使用/编写的代码.

XML DrawerLayout:

<android.support.v4.widget.DrawerLayout
    android:id="@+id/drawer_layout"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

        <FrameLayout
            android:id="@+id/content_frame"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />

        <include layout="@layout/toolbar" />

    </FrameLayout>

    <com.andrewq.planets.util.ScrimInsetsFrameLayout
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:id="@+id/linearLayout"
        android:layout_width="304dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:fitsSystemWindows="true"
        app:insetForeground="#4000">

        <ListView
            android:id="@+id/left_drawer"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:choiceMode="singleChoice" />
    </com.andrewq.planets.util.ScrimInsetsFrameLayout>


</android.support.v4.widget.DrawerLayout>

首先,如果这属于Ask Ubuntu,我很抱歉......我不确定这个论坛是什么.

我正在尝试使用PHP和shell脚本从Github派生并构建一个Android项目.基本上,我是从我写入网站的shell脚本中打印出一些输出.当您访问该页面并按下某些按钮时,该项目将使用Gradle进行分叉和构建.PHP代码运行shell脚本,然后在命令运行时将输出打印到浏览器中.

但是,我收到此错误作为我的脚本的输出:

FAILURE: Build failed with an exception.

* What went wrong:
Failed to load native library 'libnative-platform.so' for Linux amd64.

该脚本现在只是运行gradle build但我打算稍后更改...现在,我正在构建根项目并输出结果.

如果我使用--stacktrace标志运行命令,这是输出:

尝试使用Google提供的应用内结算库时,我收到了SecurityException.以下是完整的例外情况:

我想购买 Macbook Air 2013 用于 Android 和 J2EE 开发，但 Macbook Air 规格是 i5 处理器、4GB 内存和 128GB SSD。所以我的问题是：这对于开发来说是否足够好？

因此,当点击图像时,我正在尝试启动新活动,该图像将以全屏图像开始新活动.为此,我编写了以下代码:

在XML文件中定义的ImageView:

<ImageView
     android:id="@+id/sun"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     android:layout_below="@+id/sun_title"
     android:layout_centerHorizontal="true"
     android:contentDescription="@string/sun_image"
     android:src="@drawable/sun" />

这是我在单击图像时使用onClickListener来处理意图的地方:

ImageView imageView;
//begin onViewCreated Method
     ...

     final Context classContext = null;
     imageView = (ImageView) getView().findViewById(R.id.sun);

     imageView.setOnClickListener(new View.OnClickListener() {

          @Override
          public void onClick(View v) {
               Intent i = new Intent(classContext, Settings.class);
               startActivity(i);                
          }
     });

     ...
//end onViewCreated Method

我使用以下代码没有错误,但是当我运行应用程序并点击图像时,应用程序崩溃并返回nullPointerException.这是logcat:

我正在尝试使用搜索栏，以便用户可以调整片段中edittext框的值。这是我使用它的地方：

...

//NOTE: This is in the onCreateView() method for a Fragment
button.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
         seekBar.setProgress(seekBar.getProgress() + 1);
         editText.setText(String.valueOf(seekBar.getProgress()));

         //Hidden method call not needed to be visible...

         //Notice the InputMethodManager, also, this is line 197...
         InputMethodManager imm = (InputMethodManager) context.getSystemService(                                    
              Context.INPUT_METHOD_SERVICE);

         imm.hideSoftInputFromWindow(seekBar.getWindowToken(), 0);

    }
});

...

这是Logcat的输出：
