安卓开发 第六篇 我的安卓应用架构设计-----BaseActivity类

BaseActivity是我的架构设计中所有activity的基类，含有一些公共的属性和方法，同时控制toolbar的显示，以及其他一些功能。。。

来看源码：

/**

// 使用依赖注入
initInjector();

//设置根布局

// 将当前activity加入ActivityManager中
appPageManager.addActivity(this);

// 设置导航栏
toolbar = (Toolbar) find(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayShowTitleEnabled(false);

BaseActivity中的有些方法是由于项目的需要而添加的，可能在其他项目中不需要，这点请大家自行忽略。

其中BaseUiView 是所有对view操作接口的基类：

/**
* BaseUiView 是应用中所有UiView的顶级抽象类，适合抽取UiView的公共方法和属性
*
* UiView：MVP架构中的V。
*
* Created by tianlai on 16-3-3.
*/
public interface BaseUiView {

/**
* showLoading 方法主要用于页面请求数据时显示加载状态
*/
public void showLoading();

/**
* showEmpty 方法用于请求的数据为空的状态
*/
public void showEmpty();

/**
* showError 方法用于请求数据出错
*/
public void showError();

/**
* showError 方法用于请求数据完成
*/
public void loadingComplete();

}

下面来看一个具体的activity：

/**
* LoginActivity app的登录页面
* <p>
* Created by tianlai on 16-3-3.
*/
public class LoginActivity extends BaseActivity implements LoginView {

@Inject
LoginPresenter loginPresenter;

@Bind(R.id.edt_account)
EditText edtAccount;

@Bind(R.id.edt_psw)
EditText edtPsw;

@Bind(R.id.tv_login)
TextView tvLogin;

@Bind(R.id.tv_register)
TextView tvRegister;

@Bind(R.id.tv_forgetpsw)
TextView tvForgetpsw;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

View contentView = inflateView(R.layout.activity_login);

setContentViewToRoot(contentView);

ButterKnife.bind(this, contentView);

hideToolbar();

}

@OnClick({R.id.tv_login,R.id.tv_register,R.id.tv_forgetpsw})
public void OnClick(View v){
switch (v.getId()){
case R.id.tv_login:
//进行登录请求
loginPresenter.login(getPhoneNum(),getPasswd());
break;
case R.id.tv_register:
toRegisterPage();
break;

case R.id.tv_forgetpsw:
toResetPasswdPage();
break;
}
}

@Override
protected void injectActivity(ActivityComponent activityComponent) {
activityComponent.inject(this);
}

@Override
protected BasePresenter getPresenter() {
return loginPresenter;
}

@Override
public void showEmpty() {

}

@Override
public void showError() {

}

@Override
public void toRegisterPage() {
startActivity(new Intent(this,RegisterActivity.class));
}

@Override
public String getPhoneNum() {
return edtAccount.getText().toString().trim();
}

@Override
public String getPasswd() {
return edtPsw.getText().toString().trim();
}

@Override
public void toMainPage() {
startActivity(new Intent(this,MainActivity.class));

finish();
}

@Override
public void toResetPasswdPage() {
startActivity(new Intent(this,ResetPswActivity.class));
}
}

而LoginView ：

/**
*
* Created by tianlai on 16-3-3.
*/
public interface LoginView extends BaseUiView {
/**
* 去到注册页面
*/
public void toRegisterPage();

/**
* 获取登录手机号
*
* @return
*/
public String getPhoneNum();

/**
* 获取登录密码
*
* @return
*/
public String getPasswd();

/**
* 去主页面
*/
public void toMainPage();

/**
* 去重置密码页面
*/
public void toResetPasswdPage();
}

页面布局（activity_login.xml）：

<?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="match_parent"
android:background="@color/bg_login"
android:gravity="center"
android:orientation="vertical">

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:text="用户登录"
android:textColor="@color/white"
android:textSize="25sp"
android:textStyle="bold" />

<EditText
android:id="@+id/edt_account"
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_marginLeft="40dp"
android:layout_marginRight="40dp"
android:paddingLeft="8dp"
android:paddingRight="8dp"
android:maxLength="20"
android:singleLine="true"
android:textColor="@color/font_black_light"
android:textColorHint="@color/hint_color"
android:hint="@string/hint_account"
android:layout_marginTop="60dp"
android:background="@color/white" />

<EditText
android:id="@+id/edt_psw"
android:layout_width="match_parent"
android:layout_height="40dp"
android:layout_marginLeft="40dp"
android:layout_marginRight="40dp"
android:paddingLeft="8dp"
android:singleLine="true"
android:paddingRight="8dp"
android:maxLength="16"
android:textColor="@color/font_black_light"
android:textColorHint="@color/hint_color"
android:hint="@string/hint_psw"
android:layout_marginTop="20dp"
android:background="@color/white" />

<TextView
android:id="@+id/tv_login"
android:layout_width="match_parent"
android:layout_height="40dp"
android:layout_marginLeft="40dp"
android:layout_marginRight="40dp"
android:layout_marginTop="40dp"
android:background="@drawable/bg_btn_round_green_5"
android:gravity="center"
android:text="@string/login_now"
android:textColor="@color/whitesmoke"
android:textSize="18sp" />

<TextView
android:id="@+id/tv_register"
android:layout_width="match_parent"
android:layout_height="40dp"
android:layout_marginLeft="40dp"
android:layout_marginRight="40dp"
android:layout_marginTop="20dp"
android:background="@drawable/bg_btn_round_green_5"
android:gravity="center"
android:text="@string/register_now"
android:textColor="@color/whitesmoke"
android:textSize="18sp" />

<TextView
android:id="@+id/tv_forgetpsw"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="15dp"
android:gravity="center"
android:text="@string/forget_psw"
android:textColor="@color/aqua"
android:textSize="14sp" />

</LinearLayout>

最终效果：



额，发现没什么可以说的了，就到这里吧！
