博客内容展示了一段Java代码，定义了一个名为BaseActivity的抽象类，该类继承自AppCompatActivity，体现了面向对象编程中的继承特性。

public abstract class BaseActivity extends AppCompatActivity {

private T mBasePresenter;
private StatusView mStatusView;
private ErrorView mErrorView;
private BroadcastReceiver mReceiver;

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    if (initLayoutId() != 0) {
        //设置全局显示
        mErrorView = new ErrorView(this);
        ((ViewGroup) getWindow().getDecorView()).addView(mErrorView);
        initVariable();
        setContentView(initLayoutId());
        setStatusBarColor(R.color.themColor);
        AppManager.getAppManager().addActivity(this);
        initView();
        initListener();
        initData();
        setBreoadcast();
    } else {
        finish();
    }
}

public abstract void initView();

public abstract void initListener();

public abstract void initData();

public abstract int initLayoutId();

//初始化变量
public abstract void initVariable();

public abstract T initPresenter();

//设置沉浸式状态栏
public void setStatusBarColor(int color) {
    StatusBarUtil.setStatusBarColor(color);
}

@Override
public void setContentView(View view) {
    initStatuView(view);
    super.setContentView(mStatusView);
}

@Override
public void setContentView(int layoutResID) {
    View inflate = View.inflate(this, layoutResID, null);
    mStatusView = initStatuView(inflate);
    super.setContentView(mStatusView);
}

@Override
public void setContentView(View view, ViewGroup.LayoutParams params) {
    mStatusView = initStatuView(view);
    super.setContentView(mStatusView, params);
}

private StatusView initStatuView(View content) {
    StatusView.Builder builder = new StatusView.Builder(this);
    mStatusView = builder.contentView(content)
            .emptyId(R.layout.layout_empity2)
            .erroryId(R.layout.layout_error)
            .loadingId(R.layout.layout_loading)
            .build();
    return mStatusView;
}

@Override
public void onAttachedToWindow() {
    super.onAttachedToWindow();
    mBasePresenter = initPresenter();
}

@Override
public void onDetachedFromWindow() {
    super.onDetachedFromWindow();
    if (mBasePresenter != null) {
        mBasePresenter.onDestory();
    }
}

public T getPresenter() {
    return mBasePresenter;
}

public void showEmptyLayout() {

}

@Override
protected void onDestroy() {
    super.onDestroy();
    mErrorView.unRegister();
    if (mReceiver != null) {
        unregisterReceiver(mReceiver);
    }
}

//显示内容
public void showContent() {
    mStatusView.showContent();
}

//加载数据
public void showloading() {
    mStatusView.showLoading();
}
//显示空白布局
public void showEmpty(){
    mStatusView.showEmpty();

}

/**
 * 设置网络监听
 */
private void setBreoadcast() {
    mReceiver = new NetStateBroadReciver();
    IntentFilter filter = new IntentFilter();
    filter.addAction(WifiManager.WIFI_STATE_CHANGED_ACTION);
    filter.addAction(WifiManager.NETWORK_STATE_CHANGED_ACTION);
    filter.addAction(ConnectivityManager.CONNECTIVITY_ACTION);
    registerReceiver(mReceiver, filter);
}

float x1, x2;

@Override
public boolean onTouchEvent(MotionEvent event) {
    if (event.getAction() == MotionEvent.ACTION_DOWN) {
        //当手指按下的时候
        x1 = event.getX();
    }
    if (event.getAction() == MotionEvent.ACTION_UP) {
        //当手指离开的时候
        x2 = event.getX();
        if (x2 - x1 > 100) {
            finish();
        }
    }
    return super.onTouchEvent(event);
}

}
