java – 如何在我的android cardviews顶部添加颜色,如图像？

我写了一个小应用程序,它显示了几张安卓卡.但我希望能够在卡片的顶部设置颜色和标题,如下图所示,到目前为止,我还没有在网上找到任何信息如何执行此操作.所以一些帮助会很棒:-)

(到目前为止,我的代码没有完成上述任务,我的代码只生成常规的所有白色卡片视图)

我的代码到目前为止如下：

CardAdapter.java

public class CardAdapter extends RecyclerView.Adapter<>(); public="" void="">

public class MainActivity extends ActionBarActivity implements SwiperefreshLayout.onrefreshListener {
    @InjectView(R.id.mainView)
    RecyclerView mRecyclerView;
    @InjectView(R.id.refreshContainer)
    SwiperefreshLayout refreshLayout;
    private linearlayoutmanager mLayoutManager;
    private CardAdapter mAdapter;
    @Override
    protected void onCreate(Bundle savedInstanceStatE) {
        super.onCreate(savedInstanceStatE);
        setContentView(R.layout.activity_main);
        ButterKnife.inject(this);
        mRecyclerView.setHasFixedSize(true);
        refreshLayout.setOnrefreshListener(this);
        TypedValue tv = new TypedValue();
        int actionBarHeight = 0;
        if (getTheme().resolveAttribute(R.attr.actionBarSize,tv,truE)) {
            actionBarHeight = TypedValue.complexToDimensionPixelSize(tv.data,getresources().getDisplaymetrics());
        }
        refreshLayout.setProgressviewEndTarget(true,actionBarHeight);
        mAdapter = new CardAdapter();
        mRecyclerView.setAdapter(mAdapter);
        // use a linear layout manager
        mLayoutManager = new GridLayoutManager(this,1);
        mRecyclerView.setLayoutManager(mLayoutManager);
    }
    @Override
    public Boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        return true;
    }
    @Override
    public Boolean onOptionsItemSELEcted(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button,so long
        // as you specify a parent activity in AndroidManifest.xml.
        return super.onOptionsItemSELEcted(item);
    }
    @Override
    public void onrefresh() {
        mAdapter.clear();
        Handler handler = new Handler();
        handler.postDelayed(new Runnable() {
            public void run() {
                refreshLayout.setrefreshing(false);
            }
        },2500);
    }
}

activity_main.xml中

item_cardview.xml：

我给你的唯一改变是,card_view：cardCornerRadius =“8dp”>并删除了imageview(不再需要)

闪卡无法填充到卡的一半的屏幕截图：
