RecyclerView series: Open source framework BaseRecyclerViewAdapterHelper use

• This is a simple Demo, use AndroidX to see the effect.

• Simple steps to use:
• In build.gradle in the project directory, you need to add the jitpack address, otherwise the BaseRecyclerViewAdapterHelper library will not be recognized.

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

• build.gradle in the app directory:

android {
    compileSdkVersion 30
    buildToolsVersion "30.0.3"

    defaultConfig {
        ......
        minSdkVersion 16
        targetSdkVersion 30
  	   ......
    }
    ......
}
dependencies {
 	......

    implementation 'androidx.recyclerview:recyclerview:1.1.0'
    implementation 'com.github.CymChad:BaseRecyclerViewAdapterHelper:2.9.40'

}

• MainActivity code:

public class MainActivity extends AppCompatActivity {
    RecyclerView rv;
    NameAdapter adapter;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        rv = findViewById(R.id.rv);
        rv.setLayoutManager(new LinearLayoutManager(MainActivity.this));

        ArrayList<String> nameList = new ArrayList<>();
        nameList.add("刘德华");
        nameList.add("张学友");
        nameList.add("黎明");
        nameList.add("郭富城");
        nameList.add("任达华");
        nameList.add("洪金宝");
        nameList.add("周星驰");
        nameList.add("成龙");

        adapter = new NameAdapter(R.layout.itme_name, nameList);
        rv.setAdapter(adapter);
    }
}

NameAdapter code:

public class NameAdapter extends SimpleQuickAdapter<String> {
    public NameAdapter(int layoutId, @Nullable List<String> data) {
        super(layoutId, data);
    }

    @Override
    public int getItemLayoutId() {
        return R.layout.itme_name;
    }

    @Override
    protected void convert(BaseViewHolder helper, String item) {
        helper.setText(R.id.tv_name, item);
    }
}

SimpleQuickAdapter is just to simplify the NameAdapter, and often forget to pass the generic BaseViewHolder. SimpleQuickAdapter code.

public abstract class SimpleQuickAdapter<T> extends BaseQuickAdapter<T, BaseViewHolder> {
    /**
     * @return 此方法只是便于在Adapter的内部，直接看到布局id
     */
    public abstract int getItemLayoutId();


    public SimpleQuickAdapter(int layoutId, @Nullable List<T> data) {
        super(layoutId, data);
    }

}
