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：

/** * BaseActivity 是所有activity的基类，把一些公共的方法放到里面 * <p> * Created by tianlai on 16-3-3. */public abstract class BaseActivity extends AppCompatActivity implements BaseUiView {    private ActivityComponent activityComponent;    @Inject    protected LayoutInflater inflater;    @Inject    protected Context context;    @Inject    protected AppPageManager appPageManager;    protected Toolbar toolbar;    protected LinearLayout rootView;    protected BasePresenter presenter;    protected LoadingDialog loadingDialog;    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        // 使用依赖注入        initInjector();        injectActivity(activityComponent);        //设置根布局        rootView = (LinearLayout) inflateView(R.layout.activity_base);        setContentView(rootView);        // 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);        initToolbar(toolbar);        //初始化加载数据对话框        loadingDialog=new LoadingDialog(this);        loadingDialog.setCanceledOnTouchOutside(false);        loadingDialog.setCancelable(true);        loadingDialog.setOnCancelListener(new DialogInterface.OnCancelListener() {            @Override            public void onCancel(DialogInterface loadingDialog) {                presenter.cancleLoading();            }        });        //初始化Presenter        presenter = getPresenter();        if (presenter == null) {            throw new NullPointerException("presenter 不能为 Null");        } else {            presenter.oncreate(savedInstanceState, context);        }    }    /**     * 初始化Toolbar     *     * @param toolbar     */    protected void initToolbar(Toolbar toolbar) {        toolbar.setNavigationIcon(R.mipmap.ic_toolbar_navigation);        toolbar.setNavigationOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                onBackPressed();

   /**     * 隐藏Toolbar     */    protected void hideToolbar() {        toolbar.setVisibility(View.GONE);    }    /**     * 把布局变成View     *     * @param layoutId     * @return     */    protected View inflateView(int layoutId) {        return inflater.inflate(layoutId, null);    }    /**     * 设置注入器     */    private void initInjector() {        ApplicationComponent appComponent = getAppComponent();        appComponent.inject(this);        activityComponent = DaggerActivityComponent.builder()                .applicationComponent(appComponent)                .activityModule(new ActivityModule(this))                .build();

   }    /**     * 生成Toolbar右边Action按钮     *     * @param name     * @param viewId     * @return     */    @SuppressLint("NewApi")    public TextView addRightActionView(CharSequence name, int viewId) {        TextView tv_right = new TextView(context);

       Toolbar.LayoutParams layoutParams = new Toolbar.LayoutParams(Toolbar.LayoutParams.WRAP_CONTENT,                Toolbar.LayoutParams.WRAP_CONTENT);        layoutParams.rightMargin = DpUtil.dp2px(context, 10);

   }}

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！
