How to change title of Activity in Android?

Question

I am using

Window w = getWindow();
w.setTitle(\"My title\");

to change title of my current Activity but it does not seem to work.

Answer 1

Try setTitle by itself, like this:

setTitle("Hello StackOverflow");

Answer 2

If you want to change Title of activity when you change activity by clicking on the Button. Declare the necessary variables in MainActivity:

    private static final String TITLE_SIGN = "title_sign";
    ImageButton mAriesButton;

Add onClickListener in onCreate() and make new intent for another activity:

    mTitleButton = (ImageButton) findViewById(R.id.title_button);
    mTitleButton.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        Intent intent = new Intent(MainActivity.this, 
        SignActivity.class);
        String title_act = getText(R.string.simple_text).toString();
        intent.putExtra("title_act", title_act);
        startActivity(intent);
        finish();
        }
    });

SecondActivity code in onCreate():

    String txtTitle = getIntent().getStringExtra("title_act");
    this.setTitle(txtTitle);

Answer 3

This worked for me.

public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.fragment, container, false);
    getActivity().setTitle("My Title");
//...
}

If you're using onCreateOptionsMenu, you can also add setTitle code in onCreateOptionsMenu.

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.menu, menu);

    setTitle("Neue Aktivität");
    return true;
}

If you have multiple activities, you can set it like this in AndroidManifest.xml

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <activity android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name=".NumbersActivity"
        android:label="@string/category_numbers"
        android:theme="@style/category_numbers" />
    <activity
        android:name=".FamilyActivity"
        android:label="@string/category_family"
        android:theme="@style/category_family" />
    <activity
        android:name=".ColorsActivity"
        android:label="@string/category_colors"
        android:theme="@style/category_colors" />
    <activity
        android:name=".PhrasesActivity"
        android:label="@string/category_phrases"
        android:theme="@style/category_phrases" />
    <activity
        android:name=".ExperimentActivity"
        android:label="@string/category_experiment"
        android:theme="@style/category_experiment" />
</application>

Just an FYI, you can optionally do it from the XML.

In the AndroidManifest.xml, you can set it with

android:label="My Activity Title"

Or

android:label="@string/my_activity_label"

Example:

    <activity
        android:name=".Splash"
        android:label="@string/splash_activity_title" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
