小编We *_*han的帖子

我试图更新所有库,但我仍然有错误.我能够在模拟器上运行应用程序,但是当我导出APK并在真正的Android设备上运行时,该应用程序无法运行.

MinSdkVersion是8,targetSdkVersion是19.请帮忙!!!

menu.xml文件

<menu xmlns:android="http://schemas.android.com/apk/res/android" 
        xmlns:example="http://schemas.android.com/apk/res-auto">

    <item
        android:id="@+id/action_showTC"
        android:orderInCategory="100"
        android:showAsAction="never"
        android:title="Terms and Conditions"/>

    <item android:id="@+id/action_search"
          android:title="Search"
          android:orderInCategory="100"
          example:showAsAction="ifRoom|collapseActionView"
          example:actionViewClass="android.support.v7.widget.SearchView"/>

</menu>

搜索查看

@Override
public boolean onOptionsItemSelected(MenuItem item){
    if(item.getItemId() == R.id.action_showTC){
        startActivity(new Intent(MainActivity.this, T_C.class));
        return true;
    }else{
        return super.onOptionsItemSelected(item);
    }
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {

    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.main, menu);

    SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
    SupportMenuItem searchMenuItem = ((SupportMenuItem) menu.findItem(R.id.action_search));
    SearchView searchView = (SearchView) searchMenuItem.getActionView();
    searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));

    return super.onCreateOptionsMenu(menu);
}

表现

    <activity android:name="com.agehk.queue.SearchResultsActivity"
        android:parentActivityName="com.agehk.queue.MainActivity" >
        <intent-filter>
            <action android:name="android.intent.action.SEARCH" />
        </intent-filter> …

我想在Android 2.3中使用Action bar和Fragment,但是有一个错误

Type mismatch: cannot convert from android.app.ActionBar to android.support.v7.app.ActionBar

在这一排

final ActionBar bar = getActionBar();

我已经导入了android.support.v4和v7.

package com.hmkcode.android;

import android.support.v7.app.ActionBar;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.view.ViewPager;
import android.view.Menu;
import android.view.MenuItem;


public class MainActivity extends FragmentActivity {
private ViewPager pager;
private TabsAdapter mTabsAdapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    pager = new ViewPager(this);
    pager.setId(R.id.pager);
    setContentView(pager);

    final ActionBar bar = getActionBar();
    bar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);

    mTabsAdapter = new TabsAdapter(this, pager);
    mTabsAdapter.addTab(bar.newTab().setText("List Fragment 1"), List_View.class, null);
    mTabsAdapter.addTab(bar.newTab().setText("List Fragment 2"), List_View.class, null);
    mTabsAdapter.addTab(bar.newTab().setText("List …
