Android 组件化开发搭建

  模块化的开发流程

 14.我的home页面的代码如下：

@Route(path  = RouterPath.ROUTER_HOME)
public class MainActivity extends AppCompatActivity {
    @Autowired()
    String home_msg;
    private TextView mTvHome;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_home);
        ARouter.getInstance().inject(this);
        mTvHome = (TextView) findViewById(R.id.tv_home);
        mTvHome.setText(home_msg+"");
    }
}

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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"
    tools:context=".MainActivity"
    android:gravity="center">

    <TextView
        android:id="@+id/tv_home"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        />

</LinearLayout>

15.在mine的逻辑代码如下：

@Route(path = RouterPath.ROUTER_MINE)
public class MainActivity extends AppCompatActivity {
    @Autowired
    String mine_msg;
    private TextView mTvMine;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        ARouter.getInstance().inject(this);
        setContentView(R.layout.activity_mine);
        mTvMine = (TextView) findViewById(R.id.tv_mine);
        mTvMine.setText(mine_msg);

    }
}

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout 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"
    tools:context=".MainActivity">

    <TextView
        android:id="@+id/tv_mine"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="这是默认的我的界面！！！！"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

</androidx.constraintlayout.widget.ConstraintLayout>

16：在store下的代码：

@Route(path= RouterPath.ROUTER_STORE)
public class MainActivity extends AppCompatActivity {
    @Autowired
    String store_msg;
    private TextView mTvStore;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_store);
        ARouter.getInstance().inject(this);
        mTvStore = (TextView) findViewById(R.id.tv_store);

        mTvStore.setText(store_msg);
    }
}

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout 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"
    tools:context=".MainActivity">

    <TextView
        android:id="@+id/tv_store"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="这是商店的默认界面！！！！！！"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

</androidx.constraintlayout.widget.ConstraintLayout>

哈哈哈，最后警告一下，新建的module下的布局文件的名字不要全部一样的，到时候有冲突的额！！！接下来我们就可以试着运行项目了。
