Android第三方开源FloatingActionButton(com.getbase.floatingactionbutton): FloatingActionsMenu向下伸展弹出及删除包含的FloatingActionButton【4】
FloatingActionsMenu里面嵌套的普通FloatingActionButton可以在上层Java代码动态删除。同时,FloatingActionsMenu不仅可以向上弹出伸展,也可以向下弹出伸展。
写一个例子说明。
先写一个布局文件:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" xmlns:fab="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="match_parent" tools:context="zhangphil.fab.MainActivity" > <com.getbase.floatingactionbutton.FloatingActionsMenu android:id="@+id/multiple_actions_down" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentEnd="true" android:layout_alignParentRight="true" android:layout_alignParentTop="true" android:layout_margin="10dp" fab:fab_addButtonColorNormal="@color/white" fab:fab_addButtonColorPressed="@color/white_pressed" fab:fab_addButtonPlusIconColor="@color/half_black" fab:fab_addButtonSize="normal" fab:fab_expandDirection="down" fab:fab_labelStyle="@style/menu_labels_style" > <com.getbase.floatingactionbutton.FloatingActionButton android:layout_width="wrap_content" android:layout_height="wrap_content" fab:fab_colorNormal="@color/white" fab:fab_colorPressed="@color/white_pressed" fab:fab_size="mini" fab:fab_title="FAB 1" /> <com.getbase.floatingactionbutton.FloatingActionButton android:id="@+id/button_remove" android:layout_width="wrap_content" android:layout_height="wrap_content" fab:fab_colorNormal="@color/blue_semi_transparent" fab:fab_colorPressed="@color/blue_semi_transparent_pressed" fab:fab_title="点击删除" /> <com.getbase.floatingactionbutton.FloatingActionButton android:layout_width="wrap_content" android:layout_height="wrap_content" fab:fab_colorNormal="@color/white" fab:fab_colorPressed="@color/white_pressed" fab:fab_title="FAB 2" /> </com.getbase.floatingactionbutton.FloatingActionsMenu> </RelativeLayout>
其中,
fab:fab_expandDirection="down"控制FloatingActionsMenu里面包含的FloatingActionButton弹出伸展方向。
Java代码:
package zhangphil.fab; import com.getbase.floatingactionbutton.FloatingActionButton; import com.getbase.floatingactionbutton.FloatingActionsMenu; import android.app.Activity; import android.os.Bundle; import android.view.View; import android.view.View.OnClickListener; public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); //点击删除蓝色的那个按钮 final FloatingActionButton removeAction = (FloatingActionButton) findViewById(R.id.button_remove); removeAction.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { ((FloatingActionsMenu) findViewById(R.id.multiple_actions_down)).removeButton(removeAction); } }); } }
代码运行结果如图所示:
