AndroidアプリケーションでCollapsingToolbarLayoutを表示するとjava.lang.OutOfMemoryErrorが発生しますか？

Question

私のAndroidアプリケーションにCollapsingToolbarLayoutと表示されていません。誰かがどこが間違っつもり教えてくださいだろう...アプリケーションを実行した後、私はCollapsingToolbarLayoutを表示するために使用しています。このログ

誰かが私を助けてくれたらあまりにも感謝します。よろしく。このラインで

Answer 1

：

Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.ic_background_123); 

あなたは、高解像度の画像を復号しています。ライブラリとそれを管理するためにあなたがこれらのいずれかを使用できます。

Glide

picasso

をしたり、ピカソのパレットを生成する場合は、最初のthis article

Picassopalette を読んで別のライブラリですピカソでパレットを生成することができます。

か、グライドのためにこのコードを使用することができます：

Glide.with(this) 
      .load(your image path,id,...) 
      .asBitmap() 
      .into(new SimpleTarget<Bitmap>() { 
       @Override 
       public void onResourceReady(Bitmap resource, GlideAnimation<? super Bitmap> glideAnimation) { 
        Palette.Builder palette = Palette.from(resource); 
        palette.generate(new Palette.PaletteAsyncListener() { 
         @Override 
         public void onGenerated(Palette palette) { 

         } 
        }); 
       } 
      });
