我的片段中包含ViewPager的Tab(TabHost或TabContent)有一个奇怪的问题.

问题是,当我更改页面时,然后我回到带有tab和viewPager的片段,我的内容或视图消失了.

这是TabFragment的代码

package com.halo.mobi.fragment;

import java.util.ArrayList;
import java.util.List;

import android.app.Activity;
import android.content.Context;
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.v4.view.ViewPager.OnPageChangeListener;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.HorizontalScrollView;
import android.widget.TabHost;
import android.widget.TabHost.OnTabChangeListener;
import android.widget.TabHost.TabContentFactory;
import android.widget.TabWidget;
import android.widget.TextView;
import com.halo.mobi.R;

public class GameTabFragment extends Fragment {
    Activity myActivity;

    TabWidget tab;
    TabHost tabHost;
    ViewPager pager;
    HorizontalScrollView hsvTab;

    List<String> headers;

    TabPagerAdapter adapter;
    TabContentFactory fac;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated …

请帮忙,

这是我第一次使用android studio生成发布APK,尝试了几天后,我可以签署我的项目但是当我安装apk时我总是得到这个错误 ..

我需要帮助来进一步理解自定义对话框。

我创建了自定义对话框，但为什么大小不成比例，像这样..

这就是我使用自定义布局调用对话框的方式。

Dialog dialog = new Dialog(context);
dialog.setContentView(R.layout.dialog_dp3_out); //layout for dialog
dialog.setTitle("Add a new friend");

dialog.show();

这是自定义布局...
