小编bar*_*arq的帖子

构建时我收到以下错误:

这些是我的gradle依赖项

Android Studio无法正确地将我重定向到API源.当我点击任何函数时,它会反编译.class文件字节码,而不是从sdk/sources树访问正确的文件. 点击"下载"和"刷新"选项什么都不做.这对于实现监听器来说尤其令人讨厌,因为它从文档中生成函数"不带变量"的标题(即var1,var2等).我已将complie和目标SDK设置为23.我尝试重新安装SDK工具,从canary通道更新AS,使缓存无效但到目前为止没有任何帮助.我切换到API 21,它工作正常.我错过了什么？

编辑 我已经安装了API 23(SDK平台,工具,文档,资源),所以如果你想进行downvote,请发表评论.

编辑 我的build.gradle:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion '23.0.2'

    defaultConfig {
        applicationId "com.myapp.app"
        minSdkVersion 10
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.3.0'
    compile 'com.android.support:design:23.3.0'
    compile 'com.squareup.picasso:picasso:2.5.2'
    compile project(':volley')
    compile 'com.jakewharton:butterknife:7.0.1'
}

您可以在下面找到具有相同API 23设置和相同行为的空白项目(没有第三方库)的gradle输出.

我按照以下说明尝试从Luna升级到Mars:https://wiki.eclipse.org/FAQ_How_do_I_upgrade_Eclipse%3F

我将Mars存储库http://download.eclipse.org/releases/mars添加为更新站点,然后检查更新.但我得到了例外

An error occurred while collecting items to be installed

我怎样才能解决这个问题？

Google发布了更新版本的Android Studio 3.5。更新到此版本后，我在下面收到此警告：

This project uses Gradle KTS build files which are not fully supported. 
Some functions may be affected.

但是，我相信此警告仅限于使用Gradle的Kotlin DSL管理其依赖项的开发人员。而不是使用常规脚本

首先,我知道在Android中使用任务管理器/杀手并不是很糟糕,但我想知道的是,任务管理器如何Advanced Task Killer杀死其他应用程序？
我想开发一个简单的应用程序,只为了学习体验.
我尝试从我的应用程序执行Linux命令kill pid但它不起作用,也许它需要root？

那么,我如何从我的应用程序中完成此操作？我有一个简单的ListActivity,它显示当前正在运行的任务,当用户长按我要杀死该任务的项目时.

我有一个蓝色背景的按钮样式,在API 22中工作正常,但相同的按钮显示为深灰色而没有在Android 4中应用的样式.这是我的风格:

<style name="MyApp.Plain" parent="Theme.AppCompat.NoActionBar">
      <item name="android:windowBackground">@drawable/background</item>
      <item name="android:buttonStyle">@style/MyApp.Widget.Button</item>
</style>


  <style name="MyApp.Widget.Button" parent="@android:style/Widget.Button">
      <item name="android:background">@drawable/btn_blue</item>
      <item name="android:focusable">true</item>
      <item name="android:clickable">true</item>
      <item name="android:textStyle">bold</item>
      <item name="android:textSize">14sp</item>
      <item name="android:textColor">#fff</item>
      <item name="android:gravity">center_vertical|center_horizontal</item>
   </style>

我的btn_blue.xml

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

    <item android:drawable="@drawable/btn_disabled" android:state_enabled="false"/>
    <item android:drawable="@drawable/btn_pressed" android:state_enabled="true" android:state_pressed="true"/>
    <item android:drawable="@drawable/btn_normal_blue" android:state_enabled="true"/>

</selector>

和btn_normal_blue.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" >

    <gradient
        android:angle="90"
        android:endColor="#368ac6"
        android:startColor="#0e58a4" />

    <corners android:radius="20dp" />

</shape>

可能是这种行为的原因,我该如何解决这个问题？

编辑:这不支持v7:22.2.0,但适用于v7:21.0.3.除了依赖项之外,我没有更改任何内容,并将AppCompatActivity更改为ActionBarActivity.

可能这是一个Android错误.

我从Android Studio 3.1.4更新到3.2.现在同步失败并显示错误消息

尚未收到同步完成事件

怎么解决这个问题？无效的缓存/重启没有帮助.

我更新到Eclipse Mars.现在如果我将鼠标悬停在方法上,我会在黑色背景上显示黑色文字.在从Luna更新之前,我有黄色背景,黑色文字.如何为方法配置此悬停？我在Ubuntu 14.04.2 LTS上.

我有以下AlertDialog:

AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(mContext);
dialogBuilder.setTitle(R.string.title);
dialogBuilder.setMessage(mContext.getString(R.string.message));
dialogBuilder.setPositiveButton(R.string.positive, new MyOnClickListener());
dialogBuilder.setNegativeButton(R.string.negative, new MyOnClickListener());
dialogBuilder.show();

使用此ClickListener

public static class MyOnClickListener implements DialogInterface.OnClickListener{
    @Override
    public void onClick(DialogInterface dialog, int which) {
      dialog.dismiss();
    }
  }

我希望在单击任一按钮时关闭对话框,但对话框保持打开状态.

我调试了onClick方法和行

dialog.dismiss() 

正在执行,但没有任何反应.

我哪里错了,或者我该如何解决这个问题？

是否可以使用 espresso 测试记录器为多个应用程序记录测试，或者您是否需要使用 UiAutomator 为这些测试手动编写代码？

我的拉动请求中有一个提交.然后,我尝试更改我的电子邮件,并在执行此操作后强行推送更改.现在我在其他人的拉取请求中有很多提交.如何删除这些提交？

我试过重置,但其他人的提交仍然显示在pull-request中.

现在,我的分支拥有自创建主存储库以来的所有提交.
