背景
在使用RecyclerView时,经常需要针对特定的页面写viewHolder,相当繁琐。后来看到项目中采用了统一通用的viewHolder,使用相当简单。为了更加通用,对原有代码进行了抽象简化,做成了一个依赖库,直接调用即可。
先上效果图: 开源代码地址(一共四个类):
- 通用adapter基础类:BaseCommonAdapter
- 多布局通用adapter:MultipleCommonAdapter
- 单布局通用adapter:SimpleCommonAdapter
- 通用viewHolder:ViewHolder
- 工程根目录下build.gradle文件添加:
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
- app工程下build.gradle文件添加依赖:
dependencies {
implementation 'com.github.cxyzy1:commonViewHolder:0.0.2'
}
- 调用样例:
List<String> data = prepareData();
RecyclerView recyclerView = findViewById(R.id.recyclerView);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
recyclerView.setAdapter(prepareAdapter(data));
private SimpleCommonAdapter<String> prepareAdapter(List<String> data) {
return new SimpleCommonAdapter<String>(data, android.R.layout.simple_list_item_1) {
@Override
protected void onBindViewHolder(ViewHolder holder, String data, int position) {
holder.setText(android.R.id.text1, data)
.setTextColor(android.R.id.text1, Color.RED)
.setOnItemClickListener((view) ->
Toast.makeText(MainActivity.this, String.valueOf(position), Toast.LENGTH_SHORT).show()
);
}
};
}
private List<String> prepareData() {
List<String> data = new ArrayList<>(100);
for (int i = 0; i < 100; i++) {
data.add("text-" + i);
}
return data;
}
