Android的 - 构造函数ActionBarDrawerToggle未定义 [英] Android - The constructor ActionBarDrawerToggle is undefined

问题描述

我用这个code在我的OnCreate函数通过$​​ P $打开抽屉式导航pssing的应用程序图标。

I used this code in my oncreate function to open the navigation drawer by pressing the app icon.

ActionBarDrawerToggle mDrawerToggle = new ActionBarDrawerToggle(
                this,                  /* host Activity */
                (DrawerLayout) findViewById(R.id.left_drawer), /* DrawerLayout object */
                getResources().getDrawable(R.drawable.ic_drawer),  /* nav drawer icon to replace 'Up' caret */
                getString(R.string.drawer_open),  /* "open drawer" description */
                getString(R.string.drawer_close)  /* "close drawer" description */
                ) {

            /** Called when a drawer has settled in a completely closed state. */
            public void onDrawerClosed(View view) {
                getActionBar().setTitle(R.string.title_activity_add);
            }

            /** Called when a drawer has settled in a completely open state. */
            public void onDrawerOpened(View drawerView) {
                getActionBar().setTitle(R.string.drawer_title);
            }
        };

现在它说：构造ActionBarDrawerToggle（AddActivity，DrawerLayout，绘制对象，字符串，字符串）是不确定的。我已经进口android.support.v4.app.ActionBarDrawerToggle。哪里的问题？

Now it says "The constructor ActionBarDrawerToggle(AddActivity, DrawerLayout, Drawable, String, String) is undefined". I have imported android.support.v4.app.ActionBarDrawerToggle. Where's the problem?

推荐答案

构造函数是不是 ActionBarDrawerToggle（AddActivity，DrawerLayout，绘制对象，字符串，字符串）。这是 ActionBarDrawerToggle（活动，DrawerLayout，INT，INT，INT）。改变你的最后三个参数是资源ID，引用资源ID的不是结果。

The constructor is not ActionBarDrawerToggle(AddActivity, DrawerLayout, Drawable, String, String). It is ActionBarDrawerToggle(Activity, DrawerLayout, int, int, int). Change your last three parameters to be the resource IDs, not the results of referencing the resource IDs.
