Question

我对你们任何人都有很大的要求。我想在我的简单应用程序中创建第三个片段。一切正常，没有错误。我想制作最后一个片段：＆＃34; TestFragment＆＃34;当我点击片段内的那个按钮时，我想刷新它的View（点击按钮）并在该片段内加载另一个视图（相同的片段）。请帮我这样做，说明如何获得它。我在Google上阅读过，但无法找到适合此应用程序的解决方案。

这是一个简单的代码：

主要活动：

 package com.example.viewpagerexample;

import com.example.viewpagerexample.R;

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

public class MainActivity extends FragmentActivity {
    private MyAdapter mAdapter;
    private ViewPager mPager;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mAdapter = new MyAdapter(getSupportFragmentManager());

        mPager = (ViewPager) findViewById(R.id.pager);
        mPager.setAdapter(mAdapter);
    }

    public static class MyAdapter extends FragmentPagerAdapter {
        public MyAdapter(FragmentManager fm) {
            super(fm);
        }

        @Override
        public int getCount() {
            return 2;
        }

        @Override
        public Fragment getItem(int position) {
            switch (position) {
            case 0:
                return new TestFragment();
           // case 1:
             //   return new ImageFragment();
            case 1:
               return new TestFragment();
// 
            default:
                return null;
            }
        }
     }
   }

TEST FRAGMENT：

package com.example.viewpagerexample;

import com.example.viewpagerexample.R;

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;

public class TestFragment extends Fragment {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Log.e("Test", "hello");
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);

    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.test, container, false);
       // TextView textView = (TextView) view.findViewById(R.id.detailsText);
       // textView.setText("Testing");
        return view;
    }
}

测试布局：

    <?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:orientation="vertical" >

        <TextView
            android:id="@+id/textView1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="QUIZ IMPORTANT TAKE A LOOK AT THIS!!!!!"
            android:textSize="30dp" />

        <Button
            android:id="@+id/button1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Button"
            android:layout_marginLeft="30dp" />

        <TextView
            android:id="@+id/textView2"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="asdjiasdjasoldjasjdasjdlasjdksahfkadshfalidshfladshfladsfhlasdfgjl;adkglkafdgnklfdsgjpfasmga.dsnvlkasdnvkldsnflkdasjflkasdnvlkadjvodsijfosdjv;lasdvlasdjvladosijao" />

DETAILS FRAGMENT：

package com.example.viewpagerexample;

import com.example.viewpagerexample.R;

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;

public class Details extends Fragment {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Log.e("Test", "hello");
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);

    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.details, container, false);
        TextView textView = (TextView) view.findViewById(R.id.detailsText);
        textView.setText("Testing");
        return view;
    }
}

ACTIVITY_MAIN布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <android.support.v4.view.ViewPager
        android:id="@+id/pager"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
         />

</LinearLayout>

详情LYOUT：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <android.support.v4.view.ViewPager
        android:id="@+id/pager"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
         />

</LinearLayout>
