自己正在使用的BaesActivity仅供参考

自己现在使用的一个BaesActivity可能很垃圾，但是使用呢还是没有问题的。希望对一些新手有所帮助或者启发，欢迎指导，讨论

public abstract class BaseActivity extends Activity  {
    private Toast mToast;
    private long mLastBackClickTime = 0L;
    private long mExitInterval = 2000L;
    private boolean doubleBack = true;
    protected boolean isActive = true;
    private FrameLayout mBodyContent;
    private TextView fanhuiBaseactivity;
    private LinearLayout baseactivityLayout;
    private TextView base_title;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        if (!isTemplate()) {
            setContentView(getLayoutResource());
        } else {
            setContentView(R.layout.base_view);
            baseInitView();
            View view = LayoutInflater.from(this).inflate(getLayoutResource(), null, false);
            if (mBodyContent != null) {
                mBodyContent.removeAllViews();
                mBodyContent.addView(view);
            }
            if (setTitle()!= null && setTitle().length（） != 0){
                base_title.setText(setTitle());
            }
            fanhuiBaseactivity.setOnClickListener(new View.OnClickListener() {

    //加载布局

    public void toast(String s) {

            return mInputMethodManager.hideSoftInputFromWindow(this.getCurrentFocus().getWindowToken(), 0);
        }
        return super.onTouchEvent(event);
    }
}

继承baseactivity

public class ShipUnloadingList extends BaseActivity {
    @Override
    public int getLayoutResource() {
        return R.layout.布局名字;
    }
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }

    @Override
    public Intent fanhuis() {
        return null;
    }

    @Override
    public String setTitle() {
        return "title名字";
    }
//友情提示新手一下initview（）直接掉。直接书写就行， 不需要调用。

希望对大家有所帮助，新手可以多看一看，欢迎大佬前来指导改进。
