Android封装BaseActivity

Activity在我们的日常开发中应该是最为常用的组件了，基础的使用大家肯定都是会用的，但是有的时候我们需要把它封装一下，功能大概如下:

抽象出公共方法，增强代码复用的逻辑
统一管理ActionBar
统一管理Toast,Log,Dialog

直接上代码吧，好像没什么可说的了

//BaseActivity.javapublic abstract class BaseActivity extends AppCompatActivity implements DialogControl, BaseViewInterface {    private boolean _isVisible = false;    protected LayoutInflater mInflater;    protected ViewGroup mActionBar;    private LoadingUtils loading;    private String mActionBarTitle;    @Override    protected void onCreate(@Nullable Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        onBeforeSetContentLayout();        if (getLayoutId() != 0) {            LinearLayout layout = new LinearLayout(this);            layout.setOrientation(LinearLayout.VERTICAL);            if (hasBackButton()) {                mActionBar = (ViewGroup) LayoutInflater.from(this).inflate(R.layout.action_bar_layout, null);                TextView tv = (TextView) mActionBar.findViewById(R.id.action_bar_title);                tv.setText(getActionBarTitle());                mActionBar.findViewById(R.id.action_bar_back).setOnClickListener(new View.OnClickListener() {                    @Override                    public void onClick(View view) {                        Log.e("lin", "---lin--->  111111111111111111111111");                        finish();                    }                });                layout.addView(mActionBar);            }            View view = LayoutInflater.from(this).inflate(getLayoutId(), null);            layout.addView(view);            setContentView(layout);        }        ButterKnife.bind(this);        init(savedInstanceState);        initData();        initViews();    }    @Override    protected void onPause() {        super.onPause();    }    @Override    protected void onResume() {        super.onResume();    }    protected void onBeforeSetContentLayout() {    }    protected int getLayoutId() {        return 0;    }    protected View inflateView(int resId) {        return mInflater.inflate(resId, null);    }    protected String getActionBarTitle() {        return mActionBarTitle;    }    protected boolean hasBackButton() {        return false;    }    protected boolean hasActionBar() {        return false;    }    protected void init(Bundle savedInstanceState) {    }    @Override    public void showWaitDialog() {        if (_isVisible) {            return;        }        _isVisible = true;        loading = new LoadingUtils(this).setMessage("正在加载,请稍后...");        loading.show();    }    @Override    public void hideWaitDialog() {        if (_isVisible && loading != null) {            _isVisible = false;            loading.dismiss();        }    }}

//DialogControl.javapublic interface DialogControl {    public abstract void showWaitDialog();    public abstract void hideWaitDialog();}

//BaseViewInterface.javapublic interface BaseViewInterface {    void initViews();    void initData();}

以上便是对Activity的封装～
