Iappcompat v21：材料设计 ActionBar() InflateException error-inflating-class

Question

尝试将在 (appcompat v20) 中制作的应用移动到新库 appcompat v21

与：appcompat-v7:20 工作得很好

我这样做了：

ActionBarActivity implements ActionBar.TabListener, ActionBar.OnNavigationListener

还有这个：

android.view.InflateException: Binary XML file line #17: Error inflating class android.support.v7.internal.widget.ActionBarOverlayLayout

Error inflating class android.support.v7.internal.widget.ActionBarView

Answer 1

要使用新的appcompat v21，您必须：

• 扩展ActionBarActivity 而不是FragmentActivity
• 使用getSupportActionBar() 而不是getActionBar()
• 使用继承自 Theme.AppCompat 的主题。（例如 Light 或 NoActionBar）

编辑：23/04/2015

对于新的appcompat v22.1，您应该使用新的AppCompatActivity 而不是ActionBarActivity

此外，ActionBar.TabListener、ActionBar.OnNavigationListener：操作栏导航模式已被弃用内联工具栏操作栏不支持。考虑改用其他常见的导航模式。

Answer 2

问题比看起来要深得多。

我的代码是正确的。该主题中的所有建议都是相关且正确的。

原来外部库包含旧版本support-v4，不支持 MATERIAL DESIGN(appcompat-v7:21)，但只支持appcompat-v7:20

这是ActionBar() InflateException error-inflating-class.的原因

在所有外部库中更新support-v4 将解决该问题。

我在其他主题中的 build.gradle：

multiple dex files define Landroid/support/v4/.

这是工作代码...copmactv7_api5 使用...其他步骤相同

    import android.os.Bundle;
    import android.support.v4.app.Fragment;
    import android.support.v4.app.FragmentManager;
    import android.support.v4.app.FragmentPagerAdapter;
    import android.support.v4.view.ViewPager;

    import android.support.v7.app.ActionBarActivity;

public class MainActivity extends ActionBarActivity implements
        ActionBar.TabListener {

AppSectionsPagerAdapter mAppSectionsPagerAdapter;
ViewPager mViewPager;

@SuppressWarnings("deprecation")
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.admin_main_tab);

    // Create the adapter that will return a fragment for each of the three
    // primary sections
    // of the app.
    mAppSectionsPagerAdapter = new AppSectionsPagerAdapter(
            getSupportFragmentManager());

    // Set up the action bar.
    final ActionBar actionBar = getSupportActionBar();
    actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);

    // Set up the ViewPager, attaching the adapter and setting up a listener
    // for when the
    // user swipes between sections.
    mViewPager = (ViewPager) findViewById(R.id.pager);
    mViewPager.setAdapter(mAppSectionsPagerAdapter);
    mViewPager
            .setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {
                @Override
                public void onPageSelected(int position) {
                    // When swiping between different app sections, select
                    // the corresponding tab.
                    // We can also use ActionBar.Tab#select() to do this if
                    // we have a reference to the
                    // Tab.
                    actionBar.setSelectedNavigationItem(position);
                }
            });

    // For each of the sections in the app, add a tab to the action bar.
    for (int i = 0; i < mAppSectionsPagerAdapter.getCount(); i++) {
        // Create a tab with text corresponding to the page title defined by
        // the adapter.
        // Also specify this Activity object, which implements the
        // TabListener interface, as the
        // listener for when this tab is selected.
        actionBar.addTab(actionBar.newTab()
                .setText(mAppSectionsPagerAdapter.getPageTitle(i))
                .setTabListener(this));
    }
}
