Android - 应在此处传递已解析的颜色而不是资源 ID : `getResources().getColor(R.attr.colorPrimary)`

标签 android android-toolbar android-support-design android-appcompat android-palette

我正在学习本教程 Flexibal Space with Image

用于在 android 中称为 Flexibal Space with Image 的工具栏的设计模式。在此处使用 Palette 时，我陷入 java 文件中的以下错误，导致应用程序崩溃。

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

下面是我的java文件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
        }
    });

}
}

最佳答案

R.attr.colorPrimary 是颜色 ID。 像这样尝试: 

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

或 API 23+ 使用:

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