Floating pulsante di azione e l'errore

Question

sto usando libreria di supporto di progettazione

defaultConfig { 
     vectorDrawables.useSupportLibrary = true 
     ... 
} 

dependencies { 
    compile 'com.android.support:design:23.4.0' 
    compile 'com.android.support:support-v4:23.4.0' 
    ... 
} 

quando si aggiunge FloatingActionButton

<android.support.design.widget.FloatingActionButton 
    android:layout_gravity="right" 
    android:layout_margin="20dp" 
    android:tint="#fff" 
    android:src="@drawable/ic_menu_manage" 
    app:backgroundTint="#b3000000" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" /> 

a uno dei miei layout disegno inflazione biblioteca ottengo questo errore

Caused by: java.lang.IllegalArgumentException: You need to use a Theme.AppCompat theme (or descendant) with the design library. 

Ecco la mia attività principale (it has navigation drawer)

public class MapNavActivity extends AppCompatActivity 

so che dovrebbe funzionare se cambio AppCompatActivity a Activity

Tuttavia, questo non funziona per me. Ecco l'attività definita sul file manifesto

<activity 
    android:name=".MapNavActivity" 
    android:label="@string/title_activity_map_nav" 
    android:theme="@style/AppTheme.NoActionBarMain" /> 

ed ecco il tema in file di styles.xml

<style name="AppTheme.NoActionBarMain" parent="Theme.AppCompat.Light.NoActionBar"> 
     <item name="windowActionBar">false</item> 
     <item name="windowNoTitle">true</item> 
    </style> 

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar"> 
     <!-- Customize your theme here. --> 
     <item name="colorPrimary">@color/colorPrimary</item> 
     <item name="colorPrimaryDark">@color/colorPrimaryDark</item> 
     <item name="colorAccent">@color/colorAccent</item> 
    </style> 

mi sono bloccato con questo problema quasi 5 ore. Qualcuno sa come risolvere questo?

Answer 1

Ho appena provato il codice in un progetto fresco e si sta lavorando bene sulla mia macchina. Assicurati che compile 'com.android.support:appcompat-v7:23.4.0' sia nel tuo file build.gradle, quindi esegui una ricostruzione e verifica se questo è utile. Controlla anche il tuo gestore SDK per vedere se hai qualche vecchio aggiornamento che non hai ancora installato.

Answer 2

Ok vai in modo semplice.

aggiungi prima Dipendenza al tuo build.gradle.

dependencies { 
compile fileTree(dir: 'libs', include: ['*.jar']) 
testCompile 'junit:junit:4.12' 
compile 'com.android.support:appcompat-v7:23.1.1' 
compile 'com.android.support:design:23.1.1' 

}

quindi aprire il file XML e aggiungere Floating pulsante di azione.

<android.support.design.widget.FloatingActionButton 
    android:id="@+id/fab" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_gravity="bottom|end" 
    android:layout_margin="@dimen/fab_margin" 
    android:src="@android:drawable/ic_dialog_email" /> 

quindi aprire il file .java e inizializzare il pulsante galleggiante

FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab); 
    fab.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      // Click action 
      // write you code here. 
     } 
    }); 

quindi pulire il vostro progetto ed eseguirlo.

Spero che questa soluzione ti aiuti.
