android自定义控件之底部自动切换Tab布局
今天为大家分享一下,我自定义的底部切换tab布局。先看效果图吧。点击底部控件,自动变色,自动切换不同的布局。
一、首先要定义一个底部的item,layout_bottom_item.xml。也就是上图中的单个点击项目。并且居中显示。
- <?xml version="1.0" encoding="utf-8"?>
- <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
- android:layout_width="match_parent"
- android:layout_height="match_parent"
- android:background="@color/text_white">
- <RelativeLayout
- android:layout_width="wrap_content"
- android:layout_height="wrap_content"
- android:layout_centerInParent="true"
- >
- <ImageView
- android:id="@+id/tab_woicon"
- android:layout_centerHorizontal="true"
- android:layout_marginTop="@dimen/text_padding"
- android:layout_width="wrap_content"
- android:layout_height="wrap_content"
- android:background="@mipmap/tab_icon_normal"/>
- <TextView
- android:id="@+id/tab_wotext"
- android:layout_marginTop="@dimen/text_padding"
- android:layout_below="@id/tab_woicon"
- android:layout_width="wrap_content"
- android:layout_height="wrap_content"
- android:layout_centerHorizontal="true"
- android:textSize="@dimen/text_size16"
- android:text="@string/wode_task"/>
- </RelativeLayout>
- </RelativeLayout>
二、创建底部布局,layout_bottom.xml。使用include的标签,引用刚才的布局文件,并且为每一个引用布局定义自己的id。
- <?xml version="1.0" encoding="utf-8"?>
- <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
- android:layout_width="match_parent"
- android:layout_height="@dimen/bottom_height"
- android:orientation="horizontal">
- <include
- android:id="@+id/wode_order"
- android:layout_width="0dp"
- android:layout_weight="1"
- android:layout_height="match_parent"
- layout="@layout/layout_bottom_item"></include>
- <include
- android:id="@+id/history_order"
- android:layout_width="0dp"
- android:layout_weight="1"
- android:layout_height="match_parent"
- layout="@layout/layout_bottom_item"></include>
- <include
- android:id="@+id/wode_info"
- android:layout_width="0dp"
- android:layout_weight="1"
- android:layout_height="match_parent"
- layout="@layout/layout_bottom_item"></include>
- </LinearLayout>

- wode_Relativelayout = (RelativeLayout)view.findViewById(R.id.wode_order);
- history_Relativelayout = (RelativeLayout)view.findViewById(R.id.history_order);
- info_Relativelayout = (RelativeLayout)view.findViewById(R.id.wode_info);
- }
- }
四、在activity中使用我们自定义的底部控件。
1、在activity中声明我们的控件
//自定义的底部切换控件 MyBottomLayout bottom;
2、在onCreate()方法中初始化我们的控件,并为我们的控件设置我们定义好的回调方法。
bottom = (MyBottomLayout)findViewById(R.id.bottom); bottom.setOnCallbackLister(new MycallbackLister());3、在回调方法中,处理我们需要切换的页面,我这里是定义了三个不同的fragement,切换。
/**
* 实现接口切换不同的页面
*/
private class MycallbackLister implements MyBottomLayout.ICallbackLister {
@Override
public void click(int id) {
switch (id){
case R.id.wode_order:
initPageFragement(new WodeTaskFragement());
break;
case R.id.history_order:
initPageFragement(new HistoryTaskFragement());
break;
case R.id.wode_info:
initPageFragement(new WodeInfoFragement());
break;
default:
break;
}
}
}
五、我切换fragement的方法。有不懂fragement的可以查看写资料,过些天我也会写一些fragement的文章。
/*
* 动态的切换页面
* */
private void initPageFragement(Fragment fragment) {
FragmentManager manager = getSupportFragmentManager();
FragmentTransaction transaction = manager.beginTransaction();
//替换传进来的fragement
transaction.replace(R.id.my_content,fragment);
transaction.commit();
}
