I have two activities, trying to navigate from the first one to the second one by pressing a button. First one is like this:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_first);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab_new_message);
fab.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent myIntent = new Intent(FirstActivity.this, SecondActivity.class);
startActivity(myIntent);
}
});
}
And the second one is like this:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_second);
// other stuff
}
When the Floating Action Button is pressed then, absolutely nothing happens. What is wrong with my code?
Update: This is the manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="...">
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".firstActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="secondActivity"></activity>
</application>
</manifest>
And this is the code for Floating Action Button:
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
//Button button = (Button) findViewById(R.id.button);
fab.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast toast = Toast.makeText(getApplicationContext(), "Pressed!", Toast.LENGTH_LONG);
toast.show();
}
});
In XML:
<android.support.design.widget.FloatingActionButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:clickable="true"
android:id="@+id/fab"
android:tint="@android:color/white"
android:layout_alignParentBottom="true"
android:layout_alignParentEnd="true"
app:fabSize="mini"
android:layout_alignParentRight="true" />
The whole layout:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"

android:layout_alignParentRight="true" />
<ListView

</RelativeLayout>
