1.定義全域性的布林值
boolean b=false;//實現通過判斷切換 2.實現三個檢視
<LinearLayout android:id="@+id/li" android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="horizontal"> <Button android:id="@+id/add" android:layout_width="wrap_content" android:layout_height="wrap_content"android:layout_weight="1" android:text="新增"/> <Button android:id="@+id/del" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" android:text="刪除"/> <Button android:id="@+id/list" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" android:text="List"/> <Button android:id="@+id/grid" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" android:text="Grid"/> <Button android:id="@+id/flow" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" android:text="flow"/> </LinearLayout> <android.support.v7.widget.RecyclerView android:id="@+id/id_recyclerview" android:divider="#ffff0000" android:dividerHeight="10dp" android:layout_width="match_parent" android:layout_height="match_parent" />
3.定義一個按鈕,按鈕的點選事件:
@OnClick({R.id.sel, R.id.choose}) public void onViewClicked(View view) { switch (view.getId()) { case R.id.sel: break; case R.id.choose: if(b==false){ mRecyclerView.setLayoutManager(new GridLayoutManager(this,4)); mRecyclerView.addItemDecoration(new DividerGridItemDecoration(this)); b=true; }else{ mRecyclerView.setLayoutManager(new LinearLayoutManager(this)); mRecyclerView.setAdapter(mAdapter = new HomeAdapter()); mRecyclerView.addItemDecoration(new DividerItemDecoration(this, DividerItemDecoration.VERTICAL_LIST)); b=false; } break; } }
