Android App软件框架搭建
1. App软件框架搭建
1.0软件基本架构
1.1创建MainActivity并设置布局文件
布局文件如下:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android=""android:orientation="vertical"android:layout_width="match_parent"android:layout_height="match_parent"><FrameLayout android:id="@+id/fl_main"android:layout_width="match_parent"android:layout_height="0dp"android:layout_weight="1"></FrameLayout><include layout="@layout/buttom_button_main"/></LinearLayout>
其中: buttom_button_main.xml文件如下:(此处底部tab使用layout+image+text 可使用radiobutton更为简单)
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android=""android:layout_width="match_parent"android:layout_height="55dp"android:orientation="vertical"><TextView
android:background="@color/home_back_selected"android:layout_width="match_parent"android:layout_height="1dp" /><LinearLayout
android:paddingTop="2dp"android:layout_width="match_parent"android:layout_height="54dp"android:orientation="horizontal"><LinearLayout
android:id="@+id/ll_main_home"android:gravity="center"android:orientation="vertical"android:layout_weight="1"android:layout_width="50dp"android:layout_height="50dp"><ImageView
android:id="@+id/iv_main_button_home"android:src="@drawable/bottom01"android:layout_width="30dp"android:layout_height="30dp" /><TextView
android:layout_marginTop="2sp"android:text="首页"android:textSize="14sp"android:layout_width="wrap_content"android:layout_height="wrap_content" /></LinearLayout><LinearLayout android:id="@+id/ll_main_invest"android:layout_weight="1"android:gravity="center"android:orientation="vertical"android:layout_width="50dp"android:layout_height="50dp"><ImageView
android:id="@+id/iv_main_button_invest"android:src="@drawable/bottom03"android:layout_width="30dp"android:layout_height="30dp" /><TextView
android:layout_marginTop="2sp"android:text="投资"android:textSize="14sp"android:layout_width="wrap_content"android:layout_height="wrap_content" /></LinearLayout><LinearLayout android:id="@+id/ll_main_my"android:gravity="center"android:orientation="vertical"android:layout_weight="1"android:layout_width="50dp"android:layout_height="50dp"><ImageView
android:id="@+id/iv_main_button_my"android:src="@drawable/bottom05"android:layout_width="30dp"android:layout_height="30dp" /><TextView
android:layout_marginTop="2sp"android:text="我的"android:textSize="14sp"android:layout_width="wrap_content"android:layout_height="wrap_content" /></LinearLayout><LinearLayout android:id="@+id/ll_main_more"android:layout_weight="1"android:gravity="center"android:orientation="vertical"android:layout_width="50dp"android:layout_height="50dp"><ImageView
android:id="@+id/iv_main_button_more"android:src="@drawable/bottom07"android:layout_width="30dp"android:layout_height="30dp" /><TextView
android:layout_marginTop="2sp"android:text="更多"android:textSize="14sp"android:layout_width="wrap_content"android:layout_height="wrap_content" /></LinearLayout></LinearLayout>
</LinearLayout>
1.2 创建四个对应的Fragment 并加载对应的四布局文件
1) HomeFragment对应类
com.example.chen.guigup2p.fragment.HomeFragment
/*** 1. HomeFragment --首页*/public class HomeFragment extends Fragment {@Nullable@Overridepublic View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {View view = View.inflate(getContext(), R.layout.fragment_home,null);return view;}
}2)HomeFragment对应布局文件
layout/fragment_home.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android=""android:orientation="vertical" android:layout_width="match_parent"android:layout_height="match_parent"><TextView
android:text="首页"android:textSize="20sp"android:layout_width="match_parent"android:layout_height="match_parent" />
</LinearLayout>
其余三个fragment类似
1.3 实现不同Fragment间切换
1.3.1 ButterKnife 框架使用
1 安装插件
2 导入到gradle文件
dependencies {
... ...
/*使用butterknife*/compile 'com.jakewharton:butterknife:7.0.1'
}3 MainActiviy中使用ButterKnife
使用注解初始化视图对象
public class MainActivity extends FragmentActivity {@Bind(R.id.fl_main)FrameLayout flMain;@Bind(R.id.iv_main_button_home)ImageView ivMainButtonHome;@Bind(R.id.ll_main_home)LinearLayout llMainHome;@Bind(R.id.iv_main_button_invest)ImageView ivMainButtonInvest;@Bind(R.id.ll_main_invest)LinearLayout llMainInvest;@Bind(R.id.iv_main_button_my)ImageView ivMainButtonMy;@Bind(R.id.ll_main_my)LinearLayout llMainMy;@Bind(R.id.iv_main_button_more)ImageView ivMainButtonMore;@Bind(R.id.ll_main_more)LinearLayout llMainMore;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);ButterKnife.bind(this);setSelect(1);}}添加底部tab点击事件
@OnClick({R.id.ll_main_home, R.id.ll_main_invest, R.id.ll_main_my, R.id.ll_main_more})public void switchFragment(View view) {switch (view.getId()) {case R.id.ll_main_home:Toast.makeText(this, "首页", Toast.LENGTH_SHORT).show();setSelect(1);break;case R.id.ll_main_invest:Toast.makeText(this, "投资", Toast.LENGTH_SHORT).show();setSelect(2);break;case R.id.ll_main_my:Toast.makeText(this, "我的", Toast.LENGTH_SHORT).show();setSelect(3);break;case R.id.ll_main_more:Toast.makeText(this, "更多", Toast.LENGTH_SHORT).show();setSelect(4);break;}}切换fragment试图并更新按钮状态
