我想打开所有不同设备的屏幕一半的抽屉列表.我尝试将layout_margineleft 200dp或100dp的硬编码值写入抽屉列表.但它不适用于所有不同设备的设备.那么如何才能为抽屉列表保留一半的屏幕.我也尝试了各种功能,如setLeft(int)等.但由于我使用的是最低版本8,因此其中一些功能不起作用.所以请帮助我.提前致谢.

    mDrawerLayout = (DrawerLayout) view.findViewById(R.id.drawer_layout);
    mDrawerList = (ListView) view.findViewById(R.id.top_sectionlist);

xml为:

<?xml version="1.0" encoding="utf-8"?>

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

每个人都在我的应用程序中使用解析服务进行推送通知.但是当我在一台设备上重新安装应用程序时,它会一直注册.然后问题是,一台设备会在每台设备上收到多个通知.我已经完成了一些注册代码,如下所示.请帮助我,提前谢谢.

Parse.initialize(this, PARSE_APP_ID, PARSE_CLIENT_KEY);
ParseACL defaultACL = new ParseACL();
defaultACL.setPublicReadAccess(true);
ParseACL.setDefaultACL(defaultACL, true);
PushService.setDefaultPushCallback(this, MainActivity.class);
ParseInstallation.getCurrentInstallation().getInstallationId();
ParseInstallation.getCurrentInstallation().saveInBackground();

并订阅:

PushService.subscribe(this, userName, Detail.class);

在清单中

    android:protectionLevel="signature" />

  <uses-permission android:name="com.example.app.permission.C2D_MESSAGE" />

我想在文本view.I添加了复制粘贴功能,增加了代码registerForContextMenu(detailedText);,并 android:textIsSelectable="true"在xml.When我试图复制它工作得很好,但是当它指出在文本视图的第一个位置,比我们尽量选择文本它抛出错误.我在下面显示.我怎么解决呢？请帮我.

我在我们的应用程序中使用解析推送通知但在设备注册时出现一些问题,错误如下所示.当我们向设备发送推送通知时,还有一个问题,即设备收到多个通知.虽然我们也将解析库升级到Parse 1.4.1.请帮助我,提前谢谢.
