この問題を解決するには助けが必要です。私のコーディングは最初のレイアウトでしか機能せず、2 番目のレイアウトでは機能しないという問題。

これは私のタブ xml レイアウトです

<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/tabhost"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <LinearLayout
        android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent">
        <TabWidget
            android:id="@android:id/tabs"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content" />
        <FrameLayout
            android:id="@android:id/tabcontent"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"/>
    </LinearLayout>
</TabHost>

これは私のタブJavaファイルです

package watresystem.com;

import android.app.TabActivity;
import android.content.Intent;
import android.os.Bundle;
import android.widget.TabHost;
import android.widget.TabHost.TabSpec;


public class WatersystemActivity extends TabActivity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        TabHost tabHost = getTabHost();

        // Tab for Output
        TabSpec outputspec = tabHost.newTabSpec("Output");
        // setting Title and Icon for the Tab
        outputspec.setIndicator("Output", getResources().getDrawable(R.drawable.icon_output_tab));
        Intent outputIntent = new Intent(this, OutputActivity.class);
        outputspec.setContent(outputIntent);

        // Tab for Input
        TabSpec inputspec = tabHost.newTabSpec("Input");
        inputspec.setIndicator("Input", getResources().getDrawable(R.drawable.icon_input_tab));
        Intent inputIntent = new Intent(this, InputActivity.class);
        inputspec.setContent(inputIntent);

        // Tab for Time & Date
        TabSpec timespec = tabHost.newTabSpec("Time");
        timespec.setIndicator("Time", getResources().getDrawable(R.drawable.icon_time_tab));
        Intent timeIntent = new Intent(this, TimeActivity.class);
        timespec.setContent(timeIntent);

        // Adding all TabSpec to TabHost
        tabHost.addTab(outputspec); // Adding output tab
        tabHost.addTab(inputspec); // Adding input tab
        tabHost.addTab(timespec); // Adding time tab
    }
}

これがアクティビティです

public class MainActivity extends TabActivity {

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    Resources ressources = getResources(); 
    TabHost tabHost = getTabHost(); 

    // Android tab
    Intent intentAndroid = new Intent().setClass(this, AndroidActivity.class);
    TabSpec tabSpecAndroid = tabHost
      .newTabSpec("Android")
      .setIndicator("", ressources.getDrawable(R.drawable.icon_android_config))
      .setContent(intentAndroid);

    // Apple tab
    Intent intentApple = new Intent().setClass(this, AppleActivity.class);
    TabSpec tabSpecApple = tabHost
      .newTabSpec("Apple")
      .setIndicator("", ressources.getDrawable(R.drawable.icon_apple_config))
      .setContent(intentApple);

    // Windows tab
    Intent intentWindows = new Intent().setClass(this, WindowsActivity.class);
    TabSpec tabSpecWindows = tabHost
      .newTabSpec("Windows")
      .setIndicator("", ressources.getDrawable(R.drawable.icon_windows_config))
      .setContent(intentWindows);

    // Blackberry tab
    Intent intentBerry = new Intent().setClass(this, BlackBerryActivity.class);
    TabSpec tabSpecBerry = tabHost
      .newTabSpec("Berry")
      .setIndicator("", ressources.getDrawable(R.drawable.icon_blackberry_config))
      .setContent(intentBerry);

    // add all tabs 
    tabHost.addTab(tabSpecAndroid);
    tabHost.addTab(tabSpecApple);
    tabHost.addTab(tabSpecWindows);
    tabHost.addTab(tabSpecBerry);

    //set Windows tab as default (zero based)
    tabHost.setCurrentTab(2);
} 
 }

これはXML用です

<?xml version="1.0" encoding="utf-8"?>
  <TabHost xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/tabhost"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
 <LinearLayout
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:padding="5dp">
    <TabWidget
        android:id="@android:id/tabs"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" />
    <FrameLayout
        android:id="@android:id/tabcontent"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:padding="5dp" />
  </LinearLayout>
 </TabHost>
