I am a new bee to Android App Development. I am practicing the code in the Book Hello, Android . Right now I am struck with Menu and could not able to move further. I would like to present my situation in clear so that I could be guided by an experienced android app developer . I uploaded a picture showing the status. when I pressed the menu I could able to find one option called settings. But nothing happens when the settings button is pressed. I am surprised about the error and wasted lot of time to fix it. but I could not able to fix it. I want some real android app development professional to find the solution to this problem that I face and help me to proceed further. <img src="https://i.stack.imgur.com/2Xtf3.jpg" alt="enter image description here"> here is the code that i used. test/src/org/anil/test/TestActivity.java <pre><code> package org.anil.test; import android.app.Activity; import android.os.Bundle; import android.view.Menu; import android.view.MenuInflater; import android.view.MenuItem; import android.content.Intent; public class TestActivity extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); } public boolean onCreateOptionsMenu(Menu menu){ super.onCreateOptionsMenu(menu); MenuInflater inflater = getMenuInflater(); inflater.inflate(R.menu.menu, menu); return true; } public boolean onOptionsMenuSelected( MenuItem item){ switch(item.getItemId()){ case R.id.settings: startActivity(new Intent(this, Prefs.class)); return true; } return false; } } </code></pre> test/res/layout/main.xml <pre><code> <?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" > <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/hello" /> </LinearLayout> </code></pre> test/src/org/anil/test/Prefs.java <pre><code> package org.anil.test; import android.os.Bundle; import android.preference.PreferenceActivity; public class Prefs extends PreferenceActivity { protected void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); addPreferencesFromResource(R.xml.settings); } } </code></pre> test/res/menu/menu.xml <pre><code> <?xml version="1.0" encoding="UTF-8"?> <menu xmlns:android="http://schemas.android.com/apk/res/android"> <item android:id="@+id/settings" android:title="@string/settings_label" android:alphabeticShortcut="@string/settings_shortcut" /> </menu> </code></pre> test/res/xml/settings.xml <pre><code> <?xml version="1.0" encoding="UTF-8"?> <PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android" > <CheckBoxPreference android:key="music" android:title="@string/music_title" android:summary="@string/music_summary" android:defaultValue="true" /> <CheckBoxPreference android:key="hints" android:title="@string/hints_title" android:summary="@string/hints_summary" android:defaultValue="true"/> </PreferenceScreen> </code></pre> test/res/values/strings.xml <pre><code> <?xml version="1.0" encoding="utf-8"?> <resources> <string name="hello">Hello World, TestActivity!</string> <string name="app_name">Test</string> <string name="settings_label">Settings</string> <string name="settings_title">Sudoku Settings</string> <string name="settings_shortcut">s</string> <string name="music_title">Music</string> <string name="music_summary">play background music</string> <string name="hints_title">Hints</string> <string name="hints_summary">Show hints during play</string> </resources> </code></pre> test/AndroidManifest.xml <pre><code> <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="org.anil.test" android:versionCode="1" android:versionName="1.0" > <uses-sdk android:minSdkVersion="10" /> <application android:icon="@drawable/ic_launcher" android:label="@string/app_name" > <activity android:name=".TestActivity" android:label="@string/app_name" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name=".Prefs" android:label="@string/settings_title"> </activity> </application> </manifest> </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
