这次的适配器用的是BaseQuickAdapter
框架引入
在build.gradle(Project:XXXX)：
allprojects {
repositories {
...
maven { url "https://jitpack.io" }
}
}
在build.gradle(Module:app)：
//BaseQuickAdapter依赖
implementation 'com.github.CymChad:BaseRecyclerViewAdapterHelper:2.9.31'
//recyclerview依赖
implementation 'com.android.support:recyclerview-v7:26.1.0'
然后是在Activity中
public class MainActivity extends AppCompatActivity {
private TextView tvAdd;
private RecyclerView recyclerView;
private Button btnCommit;
private CohabitantAdapter cohabitantAdapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main4);
initView();
initData();
setListener();
}
private void initView() {
tvAdd = (TextView) findViewById(R.id.tv_add);
recyclerView = (RecyclerView) findViewById(R.id.recyclerView);
btnCommit = (Button) findViewById(R.id.btn_commit);
}
private void initData() {
List<Bean> beans = intiData();
recyclerView.setLayoutManager(new LinearLayoutManager(this));
cohabitantAdapter = new CohabitantAdapter(this);
recyclerView.setAdapter(cohabitantAdapter);
cohabitantAdapter.setNewData(beans);
}
private void setListener() {
//新增
tvAdd.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
cohabitantAdapter.addData(0, new Bean());
}
});
//删除
cohabitantAdapter.setOnItemChildClickListener(new BaseQuickAdapter.OnItemChildClickListener() {
@Override
public void onItemChildClick(BaseQuickAdapter adapter, View view, int position) {
switch (view.getId()) {
case R.id.tv_delete: // 点击删除
cohabitantAdapter.remove(position);
break;
}
}
});
//获取数据
btnCommit.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
List<Bean> data = cohabitantAdapter.getData();
for (Bean datum : data) {
String name = datum.getName();
String gender = datum.getGender();
}
}
});
}
public List<Bean> intiData() {
List<Bean> mData = new ArrayList<>();
for (int i = 0; i < 1; i++) {
mData.add(new Bean());
}
return mData;
}
}
activity中的xml

适配器
public class CohabitantAdapter extends BaseQuickAdapter<CheckInPerson.UnderagesBean.TzrBean, BaseViewHolder> {
public CohabitantAdapter(Activity mActivity) {
super(R.layout.item_fragment_cohabitant);
}
@Override
