Tangram

Gradle

To get a Git project into your build:

Step 1. Add the JitPack repository to your build file

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

Step 2. Add the dependency

dependencies {
    implementation 'com.github.ShortStickBoy:Tangram:5.2.8'
}

Use

Step 1. Add the TangramView to your layout file

<com.sunzn.tangram.library.view.TangramView
    android:id="@+id/tangram"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:FooterDone="@layout/state_view_done"
    app:FooterFail="@layout/state_view_fail"
    app:FooterLoad="@layout/state_view_load" />

Step 2. Bind the view id to the entity class with @LayoutAnnotation

@LayoutAnnotation(R.layout.item)
public class Item extends TangramBean {

    private String name;
    private String pass;

}

Step 3. Create ItemViewHolder, set OnClickListener and bind the view

public class ItemViewHolder extends TangramViewHolder<Item, RecyclerAdapter> {

    private final String TAG = "ItemViewHolder";

    public ItemViewHolder(final View itemView, RecyclerAdapter adapter) {
        super(itemView, adapter);
        TextView view = getView(R.id.item_tv);
        view.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Log.d(TAG, "item:" + getAdapterPosition());
            }
        });
    }

    @Override
    public void onBindViewHolder(Item model, int position, RecyclerAdapter adapter) {
        TextView view = getView(R.id.item_tv);
        view.setText("item" + position);
    }

}

Step 4. Create RecyclerAdapter, create custom ViewHolder and set view's SpanCount

public class RecyclerAdapter extends TangramAdapter implements GridSpanSizeListener {

    public RecyclerAdapter() {
        super();
        setSpanSizeListener(this);
    }

    public RecyclerAdapter(List<TangramBean> beans) {
        super(beans);
        setSpanSizeListener(this);
    }

    @Override
    public TangramViewHolder onCreateViewHolder(int viewType, View itemView) {
        switch (viewType) {
            case R.layout.item_head:
                return new HeadViewHolder(itemView, this);
            case R.layout.item:
                return new ItemViewHolder(itemView, this);
            case R.layout.foot:
                return new FootViewHolder(itemView, this);
            case R.layout.done:
                return new DoneViewHolder(itemView, this);
            case R.layout.line:
                return new LineViewHolder(itemView, this);
        }
        return null;
    }

    @Override
    public int onGetSpanCount(int viewType, GridLayoutManager manager) {
        switch (viewType) {
            case R.layout.item_head:
                return manager.getSpanCount();
            case R.layout.item:
                return manager.getSpanCount();
            case R.layout.foot:
                return 3;
            case R.layout.done:
                return 2;
            case R.layout.line:
                return manager.getSpanCount();
        }
        return manager.getSpanCount();
    }

}

Step 5. Use in activity

TangramView tangram = findViewById(R.id.tangram);
ArrayList<TangramBean> beans = new ArrayList<>();

for (int i = 0; i < 1; i++) {
    beans.add(new Item());
}
for (int i = 0; i < 9; i++) {
    beans.add(new Done());
}
for (int i = 0; i < 1; i++) {
    beans.add(new Item());
}
for (int i = 0; i < 9; i++) {
    beans.add(new Done());
}

tangram.setLayoutManager(new GridLayoutManager(this, 6));
adapter = new RecyclerAdapter();
adapter.setData(beans);
tangram.setCompatAdapter(adapter);

Attribute

Attribute	Describe	Additional
FooterLoad	Footer status for load	If you setLoadMoreListener, this value must never be null.
FooterFail	Footer status for fail	If you setLoadMoreListener, this value must never be null.
FooterDone	Footer status for done	If you setLoadMoreListener, this value must never be null.
