先看文件结构,是不是很简单
AndroidStudio2023导入方式:(旧版也一样,只是格式有一点区别而已)
1、在 build.gradle.kts(Module:app) 的 dependencies 中添加如需导入。
implementation("io.github.cymchad:BaseRecyclerViewAdapterHelper4:4.1.2")
2、添加如图代码
maven { url = uri("https://www.jitpack.io") }
3、数据对象结构【TestData】,创建一个数据对象,这个可以自定义,这里测试用,就简单一点
package com.example.testquickviewholder;public class TestData {String data01;String data02;public String getData01() {return data01;}public void setData01(String data01) {this.data01 = data01;}public String getData02() {return data02;}public void setData02(String data02) {this.data02 = data02;}
}
4、【TestAdapter】Adapter列表适配器
package com.example.testquickviewholder;import android.content.Context;
import android.view.ViewGroup;import androidx.annotation.NonNull;
import androidx.annotation.Nullable;import com.chad.library.adapter4.BaseQuickAdapter;
import com.chad.library.adapter4.viewholder.QuickViewHolder;public class TestAdapter extends BaseQuickAdapter<TestData, QuickViewHolder> {@Overrideprotected void onBindViewHolder(@NonNull QuickViewHolder quickViewHolder, int i, @Nullable TestData testData) {assert testData != null;quickViewHolder.setText(R.id.Txt_01, testData.data01);}@NonNull@Overrideprotected QuickViewHolder onCreateViewHolder(@NonNull Context context, @NonNull ViewGroup viewGroup, int i) {return new QuickViewHolder(R.layout.layout_item_test, viewGroup);}
}
5、主页面【MainActivity】
package com.example.testquickviewholder;import android.os.Bundle;
import android.view.View;
import android.widget.Toast;import androidx.annotation.NonNull;
import androidx.appcompat.app.AppCompatActivity;
import androidx.recyclerview.widget.GridLayoutManager;
import androidx.recyclerview.widget.RecyclerView;import com.chad.library.adapter4.BaseQuickAdapter;import java.util.ArrayList;public class MainActivity extends AppCompatActivity {private RecyclerView mRecyclerView;private TestAdapter mTestAdapter;private ArrayList<TestData> mTestData;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);mRecyclerView = findViewById(R.id.Recycler_View);mRecyclerView.setLayoutManager(new GridLayoutManager(MainActivity.this, 1, GridLayoutManager.VERTICAL, false));mTestData = new ArrayList<>();for (int i = 0; i < 10; i++) {TestData testData = new TestData();testData.setData01("setData01:" + i);testData.setData02("setData02:" + i);mTestData.add(testData);}mTestAdapter = new TestAdapter();mTestAdapter.addAll(mTestData);mRecyclerView.setAdapter(mTestAdapter);mTestAdapter.setOnItemClickListener(new BaseQuickAdapter.OnItemClickListener<TestData>() {@Overridepublic void onClick(@NonNull BaseQuickAdapter<TestData, ?> baseQuickAdapter, @NonNull View view, int i) {Toast("被点击的数据:" + mTestData.get(i).data01);}});mTestAdapter.setOnItemLongClickListener(new BaseQuickAdapter.OnItemLongClickListener<TestData>() {@Overridepublic boolean onLongClick(@NonNull BaseQuickAdapter<TestData, ?> baseQuickAdapter, @NonNull View view, int i) {Toast("被长按的数据:" + mTestData.get(i).data01);return false;}});}protected void Toast(String msg) {Toast.makeText(MainActivity.this, msg, Toast.LENGTH_LONG).show();}
}
6、主页面布局【activity_main】
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:app="http://schemas.android.com/apk/res-auto"xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent"tools:context=".MainActivity"><androidx.recyclerview.widget.RecyclerViewandroid:id="@+id/Recycler_View"android:layout_width="match_parent"android:layout_height="match_parent" /></androidx.constraintlayout.widget.ConstraintLayout>
7、列表Item布局【layout_item_test】
<?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"><TextViewandroid:id="@+id/Txt_01"android:layout_width="match_parent"android:layout_height="wrap_content"android:layout_margin="5dp"android:background="#E6E6E6"android:gravity="center"android:padding="5dp"android:text="item" />
</LinearLayout>
认真一点,全部复制可用。
