视图相关
一般的Activity里都会用到很多的findViewById这个方法，而且每次都要强制类型转换，这样会显得很繁琐，如果在BaseActivity里封装好，就能省事：
protected <T extends View> T findView(int id) {
return (T) findViewById(id);
}
这样只要是继承了BaseActivity就能轻松使用LinearLayout llContent = findView(R.id.ll_content);，免去了诸多类型转换的麻烦。
参考代码：
public abstract class BaseActivity extends FragmentActivity implements
OnClickListener {
/** 是否沉浸状态栏 **/
private boolean isSetStatusBar = true;
/** 是否允许全屏 **/
private boolean mAllowFullScreen = true;
/** 是否禁止旋转屏幕 **/
private boolean isAllowScreenRoate = false;
/** 当前Activity渲染的视图View **/
private View mContextView = null;
/** 是否输出日志信息 **/
private boolean isDebug;
private String APP_NAME;
protected final String TAG = this.getClass().getSimpleName();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
isDebug = MApplication.isDebug;
APP_NAME = MApplication.APP_NAME;
$Log(TAG + "-->onCreate()");
try {
Bundle bundle = getIntent().getExtras();
initParms(bundle);
mContextView = LayoutInflater.from(this)
.inflate(bindLayout(), null);
