为什么 DrawerLayout 和 ActionBar 在平板电脑上不起作用？答案

【问题标题】：Why DrawerLayout and ActionBar not working on Tablets?为什么 DrawerLayout 和 ActionBar 在平板电脑上不起作用？
【发布时间】：2014-05-08 05:12:28
【问题描述】：

我正在开发一些带有滑动菜单的应用程序。当我尝试在我的 Galaxy 4s（api 18+ 4.3.3）上运行它时，它工作正常！但是当我在 xperia arc (api 8 ver 2.3.4) 上运行它时，应用程序崩溃了。我知道它依赖于支持库，我使用：导入 android.support.v4.app.ActionBarDrawerToggle；导入android.support.v4.widget.DrawerLayout；

我需要使用：

import android.support.v7.app.ActionBar;

所以我在我的项目中添加了支持库并将支持库连接到他。

但我不知道如何处理支持以及我需要对我的代码进行哪些修改：

我的 java 代码 (v4){

import android.support.v4.app.ActionBarDrawerToggle;
import android.support.v4.widget.DrawerLayout;

public class MainActivity extends Activity implements OnClickListener, OnLongClickListener , OnTouchListener , OnItemClickListener{
/////////////////
ArrayList<ItemInSetting > listSetting = new ArrayList<ItemInSetting>();
CustomAdapterSetting adapterSetting;
DrawerLayout drawer;
ActionBarDrawerToggle toggle;
//////////////////

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    settingItems();
     }

public void settingItems(){

    getActionBar().setHomeButtonEnabled(true);
    getActionBar().setDisplayHomeAsUpEnabled(true);
    drawer = (DrawerLayout) findViewById(R.id.drawer);
    toggle = new ActionBarDrawerToggle(this, drawer, R.drawable.ic_drawer, 0, 0){

        @Override
        public void onDrawerOpened(View drawerView) {
            getActionBar().setTitle("menu");

            invalidateOptionsMenu();
        }

        @Override
        public void onDrawerClosed(View drawerView) {
            getActionBar().setTitle("app title");
            invalidateOptionsMenu();
        }

    };drawer.setDrawerListener(toggle);

    listSetting.add(new ItemInSetting("ist1", R.drawable.calende_bigg));
    listSetting.add(new ItemInSetting("ist2", R.drawable.calende_bigg));
    listSetting.add(new ItemInSetting("ist3", R.drawable.calende_bigg));
    listSetting.add(new ItemInSetting("ist4", R.drawable.calende_bigg));

    lvSetting = (ListView) findViewById(R.id.listSetting);
    lvSetting.setOnItemClickListener(this);
    adapterSetting = new CustomAdapterSetting(listSetting, this);
    lvSetting.setAdapter(adapterSetting);
}

@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
        long id) {
    date = new Date();
    switch (position) {

    case 0:
        Intent intent = new Intent (MainActivity.this,ListOfHours.class);
        startActivity(intent);

        break;      
    case 1:
        getSetting();

        if(sickIsOn){
            cancelingFreeday(false);
        }else{
            addingManualMenu();
        }

        break;      
    case 2:
        changingSetting(" ");
        break;
    case 3:

        sendContact();
        break;

    default:
        break;
    }
    drawer.closeDrawers();
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // toggle nav drawer on selecting action bar app icon/title

    if (toggle.onOptionsItemSelected(item)) {
        return true;
    }
      // Handle action bar actions click
    switch (item.getItemId()) {
    case R.id.action_settings:
        return true;
    default:
        return super.onOptionsItemSelected(item);
    }
}

@Override
protected void onPostCreate(Bundle savedInstanceState) {
    super.onPostCreate(savedInstanceState);
    // Sync the toggle state after onRestoreInstanceState has occurred.

    toggle.syncState();
}

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
    // Pass any configuration change to the drawer toggls

    toggle.onConfigurationChanged(newConfig);
}

我的 xml：

这是我的项目： http://speedy.sh/UKsrV/SlidingMenu.zip 如果有人可以修复该代码并将其还给我，我将不胜感激

我该如何解决这个问题？！！请帮帮我:(((

我解决了这个问题，但知道我的平板电脑崩溃了。

【问题讨论】：

没有人会修复您的代码并将其发回。我已经发布了需要做的更正。
但仍然无法正常工作:(我在这个应用程序上有很多用户超过 10,000 名，这对我来说很重要，可以为他们提供他们需要的所有支持
我发布了一个包含完整示例的链接。休息由你来纠正

标签： java android android-actionbar drawerlayout

【解决方案1】：

ActionBar 在 api 级别 11 中可用。要支持低于 api 级别 11，您需要使用支持库中的 AppCompat。在你的android项目中引用AppCompat。

您需要扩展ActionBarActivity。在清单中使用派生自Theme.AppCompat 的主题并使用getSupportActionBar()。

完整示例@

Navigation Drawer with backword compatibility android

勾选使用资源添加库
