Android(安卓)基于BaseActivity封装

1.前言

一般来说，BaseActivity是根据项目的业务逻辑和需求封装的，每个项目的业务逻辑不一样，肯定封装的也有所差异，以下就是我根据之前开发的项目总结了一些，经供参考:

public abstract class BaseActivity extends AppCompatActivity {    private boolean isExit = false; // 是否退出按钮的转态标记    protected Context mContext;    protected final int DEFAULT_STATUS_BAR_ALPHA = 30;    protected int page = 1;    protected int count = 20;    protected boolean canLoadmore = true;    protected Unbinder mbinder;    protected Toast toast = null;    private static final String TAG = "BaseActivity";    @Override    protected void onCreate(Bundle savedInstanceState)    {        super.onCreate(savedInstanceState);        setContentView(getLayout());        mContext = this;        mbinder=ButterKnife.bind(this);        initDate();    }    /**     * 设置沉浸式标题栏 图片的     */    protected void setStatusBarTranslucent() {        StatusBarUtil.setTranslucent(this, DEFAULT_STATUS_BAR_ALPHA);    }    /**     * 设置沉浸式标题栏 标题栏的颜色     */    protected void setStatusBarColor(int color) {       StatusBarUtil.setColor(this, ContextCompat.getColor(mContext, color),       DEFAULT_STATUS_BAR_ALPHA);    }    /**     * 设置沉浸式标题栏 里面是Fragment     */    protected void setStatusBarColorInFragment() {        StatusBarUtil.setTranslucentForImageViewInFragment(this, DEFAULT_STATUS_BAR_ALPHA, null);    }//    @Override//    protected LinearLayout.LayoutParams generateTitleViewLayoutParams()//    {//        LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, SDResourcesUtil.getDimensionPixelSize(R.dimen.height_title_bar));//        return params;//    }    protected abstract int getLayout();  //  protected abstract void initView(Bundle savedInstanceState);    protected abstract void initDate();    protected void showToast(String message) {        if (!TextUtils.isEmpty(message)) {            if (toast == null) {                toast = Toast.makeText(mContext, message, Toast.LENGTH_SHORT);            } else {                toast.setText(message);            }            toast.show();        }    }    @Override    protected void onResume() {        super.onResume();    }    protected void openActivity(Class<?> pClass) {        openActivity(pClass, null);    }    /**     * 打开一个新的activity 之前的activity 都清除了     *     * @param pClass     */    protected void openActivityByNew(Class<?> pClass) {        Intent i = new Intent(this, pClass);        i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP);        startActivity(i);    }    /**     * 跳转页面     *     * @param pClass  跳转的页面     * @param pBundle 传递过去的参数     */    protected void openActivity(Class<?> pClass, Bundle pBundle) {        Intent intent = new Intent(this, pClass);        if (pBundle != null) {            intent.putExtras(pBundle);        }        startActivity(intent);        // 动画效果        // overridePendingTransition(R.anim.zoomin, R.anim.zoomout);    }    /**     * 启动带结果的Activity     *     * @param pClass     * @param pBundle     * @param requestCode     */    protected void openActivityForResult(Class<?> pClass, Bundle pBundle, int requestCode) {        Intent intent = new Intent(this, pClass);        if (pBundle != null) {            intent.putExtras(pBundle);            startActivityForResult(intent, requestCode);        } else {            startActivityForResult(intent, requestCode);        }    }    /**      * 关闭所有Activity      */      public static void finishAll() {          List copy;          synchronized (mActivities) {              copy = new ArrayList(mActivities);          }          for (BaseActivity activity : copy) {              activity.finish();          }      }      /**      * 关闭所有Activity，除了参数传递的Activity      */      public static void finishAll(BaseActivity except) {          List copy;          synchronized (mActivities) {              copy = new ArrayList(mActivities);          }          for (BaseActivity activity : copy) {              if (activity != except)                  activity.finish();          }      }     /**     * 双击退出程序     */    protected void exitBy2click() {        Timer eExit = null;        if (isExit == false) {            isExit = true;            Toast.makeText(BaseActivity.this, "再按一次退出程序", Toast.LENGTH_SHORT).show();            eExit = new Timer();            eExit.schedule(new TimerTask() {                @Override                public void run() {                    isExit = false;                }            }, 2000);        } else {            finish();            System.exit(0);        }    }    public void finish() {        super.finish();        // 动画效果        // overridePendingTransition(R.anim.zoomin, R.anim.zoomin);    }    public void defaultFinish() {        super.finish();    }    @Override    protected void onPause() {        super.onPause();    }    @Override    protected void onActivityResult(int requestCode, int resultCode, Intent data) {        // TODO Auto-generated method stub        super.onActivityResult(requestCode, resultCode, data);    }    @Override    protected void onDestroy() {        super.onDestroy();        mbinder.unbind();    }    public static final int PERMISSION_REQUEST_CODE = 0x0001;    public static PermissionListeren mLsteren = null;    public static int REQUEST_CODE = 0;    public static void requestPermission(int requestCode, PermissionListeren listeren, String... permission) {        REQUEST_CODE = requestCode;        List permissionList = new ArrayList<>();        Activity activity = ActivityManagerUtils.getInstance().getTopActivity();        mLsteren = listeren;        for (String s : permission) {            if (ContextCompat.checkSelfPermission(activity, s) != PackageManager.PERMISSION_GRANTED) {                permissionList.add(s);            }        }        if (!permissionList.isEmpty()) {            ActivityCompat.requestPermissions(activity, permissionList.toArray(new String[permissionList.size()]),                    PERMISSION_REQUEST_CODE);        } else {            listeren.onGranted(REQUEST_CODE);        }    }    /**     * 请求权限     */    protected void requestPermissions(int code, String... permissions) {        ActivityCompat.requestPermissions(this, permissions, code);        SDToast.showToast("如果拒绝授权,会导致应用无法正常使用");    }    @Override    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {        switch (requestCode) {            case PERMISSION_REQUEST_CODE:                if (grantResults.length > 0) {                    List permissionDenieds = new ArrayList<>();                    List noReminderPermissions = new ArrayList<>();                    for (int i = 0; i < grantResults.length; i++) {                        String permission = permissions[i];                        if (grantResults[i] == PackageManager.PERMISSION_DENIED) {                            permissionDenieds.add(permission);                            if (!ActivityCompat.shouldShowRequestPermissionRationale(this, permission)) {                                noReminderPermissions.add(permission);                            }                        }                    }                    if (!permissionDenieds.isEmpty()) {                        mLsteren.onDenied(REQUEST_CODE, permissionDenieds, noReminderPermissions);                    } else {                        mLsteren.onGranted(REQUEST_CODE);                    }                }                break;            default:                super.onRequestPermissionsResult(requestCode, permissions, grantResults);                break;        }    }    public interface PermissionListeren {        //全部同意授权        void onGranted(int requestCode);        /**         * 不同意授权         *         * @param deniedPermissions     未同意但是没有点不再提醒         * @param noReminderPermissions 未同意并且点了不再提醒         */        void onDenied(int requestCode, List deniedPermissions, List noReminderPermissions);    }}

2.补充(上面沉浸式其他还有N多种方法,比如)

 public static void setStatusColor(Activity context, int color) {        context.getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);        context.getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);        SystemBarTintManager tintManager = new SystemBarTintManager(context);        tintManager.setStatusBarTintColor(context.getResources().getColor(color));        tintManager.setStatusBarTintEnabled(true);        tintManager.setNavigationBarTintEnabled(false);    }

3.今天的分享到这样哈，其实还有一些你们可以根据自己需要自己加上去，比如Toobar等等..
