androidactivity自定义父类

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());
        }
    }
}
