我的MainActivity:我的应用程序已停止工作?
public class MainActivity extends FragmentActivity implements ActionBar.TabListener {
private ViewPager viewPager;
private ActionBar actionBar;
private TabsFragmentPagerAdapter tabsAdapter;
private String[] days = new String[]{"Monday","Tuesday"};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
viewPager = (ViewPager) findViewById(R.id.viewPager);
tabsAdapter = new TabsFragmentPagerAdapter(getSupportFragmentManager());
viewPager.setAdapter(tabsAdapter);
actionBar = getActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
for(int i=0; i<3; i++){
actionBar.addTab(actionBar.newTab().setText(days[i]).setTabListener(this));
}
viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageSelected(int arg) {
// TODO Auto-generated method stub
actionBar.setSelectedNavigationItem(arg);
}
@Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
// TODO Auto-generated method stub
}
@Override
public void onPageScrollStateChanged(int arg0) {
// TODO Auto-generated method stub
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
@Override
public void onTabReselected(Tab arg0, FragmentTransaction arg1) {
// TODO Auto-generated method stub
}
@Override
public void onTabSelected(Tab tab, FragmentTransaction arg1) {
// TODO Auto-generated method stub
viewPager.setCurrentItem(tab.getPosition());
}
@Override
public void onTabUnselected(Tab arg0, FragmentTransaction arg1) {
// TODO Auto-generated method stub
}
我的清单:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.muhammad_taha.tablelayout" >
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
而我下面的代码:
public class MondayFragment extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
View view = inflater.inflate(R.layout.fragment_monday, container, false);
return view;
}
}
而下一个:
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class TuesdayFragment extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
View view = inflater.inflate(R.layout.fragment_tuesday, container, false);
return view;
}
}
而对于堆栈跟踪排序的:
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
public class TabsFragmentPagerAdapter extends FragmentPagerAdapter {
public TabsFragmentPagerAdapter(FragmentManager fm) {
super(fm);
// TODO Auto-generated constructor stub
}
@Override
public Fragment getItem(int index) {
// TODO Auto-generated method stub
if(index == 0)
return new MondayFragment();
if(index == 1)
return new TuesdayFragment();
return null;
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return 3;
}
}
我的XML文件,第一页显示:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="Monday"
android:textSize="40dp"
android:gravity="center" />
</LinearLayout>
我的XML文件显示第二个选项卡:年底

嗯,我想告诉你,我坚持那从3天开始。请更正此代码。 “TabListener”界面不可用。 但通过忽略它,并在几毫秒后运行我的应用程序,然后bhoooo“不幸的是你的应用程序已停止工作”............ 请帮助我.....并且写出正确的代码我..........现在大脑完成了......而我完成了。我真的不知道后台发生了什么。我想帮助解决这个问题。如果我知道什么是问题,我可以自己解决。如果您知道解决方案,我需要帮助来发现问题。如果你需要其他文件告诉我,我会加载它。 但帮助我。
嗨,它真的很难在这里得到一些帮助,如果你发布这样一个问题...大写它想大喊一声:和犯规很好地解释你的问题...... –
对不起......关于那个 –
我是新人。对不起..... –
