其他的不多说了!我们来看看效果吧
一、实现方式一:直接引入compile方式
Add the dependency to your build.gradle:
compile ‘com.github.michaldrabik:tapbarmenu:1.0.5'
布局设计
<RelativeLayout 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" android:background="@color/dark_gray" tools:context=".MainActivity"> <!--中间按钮颜色--> <!--app:tbm_backgroundColor="@color/red"--> <!--是否初始进入页面就可以看到item图片--> <!--app:tbm_showItems="true"--> <!--中间按钮大小--> <!--app:tbm_buttonSize="30dp"--> <!--中间按钮位置--> <!--app:tbm_buttonPosition="center"--> <!--中间按钮位置左边距--> <!--app:tbm_buttonMarginLeft="0dp"--> <!--中间按钮位置右边距--> <!--app:tbm_buttonMarginRight="0dp"--> <!--中间按钮自定义图标打开状态。必须是一个向量可拉的动画。--> <!-- app:tbm_iconOpened="@drawable/icon"--> <!--中间按钮自定义图标关闭状态。必须是一个向量可拉的动画。--> <!--app:tbm_iconOpened="@drawable/icon"--> <!--中间按钮打卡item显示位置--> <!--app:tbm_menuAnchor="bottom"--> <com.michaldrabik.tapbarmenulib.TapBarMenu android:id="@+id/tapBarMenu" android:layout_width="match_parent" android:layout_height="56dp" android:layout_alignParentBottom="true" android:layout_marginBottom="24dp" app:tbm_backgroundColor="@color/red" app:tbm_buttonMarginLeft="0dp" app:tbm_buttonMarginRight="0dp" app:tbm_buttonPosition="center" app:tbm_buttonSize="30dp" app:tbm_iconClosed="@drawable/icon" app:tbm_iconOpened="@drawable/icon" app:tbm_menuAnchor="bottom" app:tbm_showItems="false"> <ImageView android:id="@+id/item1" android:layout_width="0dp" android:layout_height="match_parent" android:layout_weight="1" android:paddingBottom="10dp" android:paddingTop="10dp" android:src="@drawable/ic_person" tools:visibility="visible" /> <ImageView android:id="@+id/item2" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="1" android:paddingBottom="10dp" android:paddingTop="10dp" android:src="@drawable/ic_location" /> <Space android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="1" /> <ImageView android:id="@+id/item3" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="1" android:paddingBottom="10dp" android:paddingTop="10dp" android:src="@drawable/ic_thumb_up" /> <ImageView android:id="@+id/item4" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="1" android:paddingBottom="10dp" android:paddingTop="10dp" android:src="@drawable/ic_thumb_down" /> </com.michaldrabik.tapbarmenulib.TapBarMenu> </RelativeLayout>
在Activity中的代码
import android.os.Bundle; import android.support.v7.app.AppCompatActivity; import android.util.Log; import android.view.View; import android.widget.Toast; import com.michaldrabik.tapbarmenulib.TapBarMenu; import butterknife.Bind; import butterknife.ButterKnife; import butterknife.OnClick; public class MainActivity extends AppCompatActivity { @Bind(R.id.tapBarMenu) TapBarMenu tapBarMenu; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); ButterKnife.bind(this); } private boolean isClick = true; @OnClick(R.id.tapBarMenu) public void onMenuButtonClick() { // if (isClick) { // tapBarMenu.toggle(); // isClick = false; // } tapBarMenu.toggle(); } @OnClick({R.id.item1, R.id.item2, R.id.item3, R.id.item4}) public void onMenuItemClick(View view) { // tapBarMenu.close(); switch (view.getId()) { case R.id.item1: Toast.makeText(this,"item1",Toast.LENGTH_LONG).show(); break; case R.id.item2: Toast.makeText(this,"item2",Toast.LENGTH_LONG).show(); break; case R.id.item3: Toast.makeText(this,"item3",Toast.LENGTH_LONG).show(); break; case R.id.item4: Toast.makeText(this,"item4",Toast.LENGTH_LONG).show(); break; } } }
到这里效果就基本实现了
二、实现方式二:引入Module方式
module中记得引入
