Android - Sollten statt Ressource-ID hier aufgelöste Farbe Pass: `GetResources() getColor (R.attr.colorPrimary)`

Question

Ich verfolge dieses Tutorial Flexibal Space with Image

Für Design-Muster für eine Symbolleiste Flexibal Raum genannt mit Bild in Android. Bei der Verwendung von Palette hier bin ich in folgenden Fehler in java Datei stecken verursacht Anwendung zum Absturz.

Should pass resolved color instead of resource id here: `getResources().getColor(R.attr.colorPrimary)` 

Follwing ist meine Java-Datei YoutubeActivity.java

public class YoutubeActivity extends AppCompatActivity { 

Toolbar toolbar; 
CollapsingToolbarLayout collapsingToolbar; 
int mutedColor = R.attr.colorPrimary; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_youtube); 

    toolbar = (Toolbar) findViewById(R.id.anim_toolbar); 
    setSupportActionBar(toolbar); 

    collapsingToolbar = (CollapsingToolbarLayout) findViewById(R.id.collapsing_toolbar); 
    collapsingToolbar.setTitle("Praval Sharma"); 
    ImageView header = (ImageView) findViewById(R.id.header); 

    Bitmap bitmap = BitmapFactory.decodeResource(getResources(), 
      R.drawable.header); 
    Palette.from(bitmap).generate(new Palette.PaletteAsyncListener() { 
     @Override 
     public void onGenerated(Palette palette) { 
      mutedColor = palette.getMutedColor(R.attr.colorPrimary); //error 
      collapsingToolbar.setContentScrimColor(mutedColor);  //error 
     } 
    }); 

} 
}

Answer 1

Fügen Sie diese zu Ihrem Thema

<item name="windowActionBar">false</item> 
<item name="windowNoTitle">true</item> 

Manifest:

<activity android:name=".YoutubeActivity" 
android:theme="@style/AppTheme.NoActionBar"> 
     <intent-filter> 
      <action android:name="android.intent.action.MAIN" /> 

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

Answer 2

R.attr.colorPrimary ist die Farbe ID. es so versuchen:

mutedColor = palette.getMutedColor(getResources().getColor(R.attr.colorPrimary)); 
collapsingToolbar.setContentScrimColor(mutedColor); 

oder für API 23+ Verwendung:

ContextCompat.getColor(context, R.attr.colorPrimary); 

Answer 3

Try R.color.colorPrimary statt R.at.colorPrimary. Spezifizieren Sie Farben in Farben.XML-Datei in res/Werte

Answer 4

die int als ColorInt deklarieren wie folgt

@ColorInt int mutedColor

Answer 5

ich genau das gleiche Problem konfrontiert, und hier ist meine Lösung für dieses,

mutedColor = palette.getMutedColor(ContextCompat.getColor(getApplicationContext(), R.color.colorPrimary);); 
collapsingToolbar.setContentScrimColor(mutedColor); 

Hope Diese hilft! ..

Update: Ich weiß, es klingt komisch/dumm, ich habe nur die Inspektion deaktiviert Das ist kein Kompilierzeitfehler und kein Laufzeitfehler. Ich wollte dich nur wissen lassen, Jungs.
