recyclelview實現listview條目展示以及監聽事件

1.添加依賴

compile 'com.android.support:recyclerview-v7:25.0.0'

2.佈局

activity_main.xml

<android.support.v7.widget.RecyclerView
    android:id="@+id/recyclerView"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

layout_item.xml

<TextView
    android:id="@+id/tv"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="李白" />

3.代碼

        for (int i = 0;i<20;i++){
            list.add("條目展示:"+i);
        }
        //管理器
        LinearLayoutManager manager = new LinearLayoutManager(MainActivity.this);
        recyclerView.setLayoutManager(manager);
