android activity自定义抽象父类

android开发最常用的组件就是activity，但是activity中也有很多常用的方法，几乎每次建立activity后都需要调用的一些方法流程，在此自定义一个父类-BaseActivity，使所有的activity都继承于这个父类，继承以后会自动继承父类的方法，并集成了一些界面跳转动画等公共效果，
BaseActivity.java

public abstract class BaseActivity extends AppCompatActivity {    protected Context mContext;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView();        setContentView(R.layout.activity_base_layout);        initParent();        findViews();        setListensers();        MyApplication myApplication = (MyApplication) getApplication();        myApplication.addTempActivityInBackStack(this);    }    @Override    protected void onActivityResult(int arg0, int arg1, Intent arg2) {        // TODO Auto-generated method stub        super.onActivityResult(arg0, arg1, arg2);    }    private void initParent() {        mContext = this;        LinearLayout subCententView = (LinearLayout) this.findViewById(R.id.base_sub_activty_layout);        LayoutParams layoutParams = new LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,                ViewGroup.LayoutParams.MATCH_PARENT);        View centerView = View.inflate(mContext, setContentView(), null);        subCententView.addView(centerView, layoutParams);    }    protected boolean isShowNoNetworksPrompt() {        return true;    }    /**     * 跳转到某个Activity     */    protected void gotoActivity(Context mContext, Class<?> toActivityClass, Bundle bundle) {        Intent intent = new Intent(mContext, toActivityClass);        if (bundle != null) {            intent.putExtras(bundle);        }        mContext.startActivity(intent);        ((Activity) mContext).overridePendingTransition(R.anim.push_right_in, R.anim.not_exit_push_left_out);//页面跳转动画    }    /**     * 退出到某个Activity     */    protected void backActivity() {        finish();        overridePendingTransition(R.anim.not_exit_push_left_in, R.anim.push_right_out);//页面退出动画    }    @Override    public boolean onKeyDown(int keyCode, KeyEvent event) {        // 所有需要统一处理的onKeyDown写在这个if里面        if (isOnKeyDown()) {            if (keyCode == KeyEvent.KEYCODE_BACK) {                backActivity();            }        }        return super.onKeyDown(keyCode, event);    }    protected boolean isOnKeyDown() {        return true;    }    /**     * 加载子类布局     */    protected abstract int setContentView();    /**     * 加载控件     */    protected abstract void findViews();    /**     * 设置监听     */    protected abstract void setListensers();    @Override    protected void onResume() {        super.onResume();        MyApplication myApplication = (MyApplication) getApplication();        myApplication.setResumeContext(this);        if (JPushInterface.isPushStopped(getApplicationContext())) {            JPushInterface.resumePush(getApplicationContext());        }    }}
