小编use*_*746的帖子

我有一个RecyclerView适配器,如下所示:

public class RecyclerAdapter extends RecyclerView.Adapter<RecyclerAdapter.ViewHolder> {

    private static Context context;
    private List<Message> mDataset;

    public RecyclerAdapter(Context context, List<Message> myDataset) {
        this.context = context;
        this.mDataset = myDataset;
    }

    public static class ViewHolder extends RecyclerView.ViewHolder implements View.OnCreateContextMenuListener, View.OnClickListener {
        public TextView title;
        public LinearLayout placeholder;

        public ViewHolder(View view) {
            super(view);
            view.setOnCreateContextMenuListener(this);

            title = (TextView) view.findViewById(R.id.title);
            placeholder = (LinearLayout) view.findViewById(R.id.placeholder);
        }
    }

    @Override
    public RecyclerAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.message_layout, parent, false);
        ViewHolder vh = new ViewHolder((LinearLayout) view);

        return …

我有一个这样的图层列表：

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape android:shape="oval">
            <solid android:color="@color/black" />
        </shape>
    </item>

    <item
        android:drawable="@drawable/ic_pin"
        android:adjustViewBounds="true"
        android:scaleType="fitXY" />
</layer-list>

如何以编程方式更改形状和可绘制对象的颜色？

例如，如何#FF0000以@drawable/ic_globe编程方式更改颜色并将可绘制对象更改为？

我有一个布局,images.xml我想加载/膨胀到另一个布局,main.xml.

这是主要布局,main.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <TextView
        android:id="@+id/title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        />

    // Load into placeholder
    <LinearLayout
        android:id="@+id/placeholder"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        />

    <TextView
        android:id="@+id/desc"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        />

</LinearLayout>

这里是images.xml我要加载到上面布局的布局:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical">

    <ImageView
        android:id="@+id/image"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        />

</LinearLayout>

我使用RecyclerView适配器将数据加载到主布局中,这是我想要加载/扩展子布局的地方:

public class RecyclerAdapter extends RecyclerView.Adapter<RecyclerAdapter.ViewHolder> {

    private static Context context;
    private List<Message> mDataset;

    public RecyclerAdapter(Context context, List<Message> myDataset) {
        this.context = context;
        this.mDataset = myDataset;
    } …
