android - ActionBarDrawerToggle 没有合适的构造函数可绘制

Question

我有简单的代码来创建简单的抽屉导航，但是当我为 ActionBarDrawerToggle 声明参数时，它说无法应用可绘制图标...

Gradle 按摩构建

Error:(36, 26) error: no suitable constructor found for     
ActionBarDrawerToggle(MainActivity,DrawerLayout,int,int,int)
constructor ActionBarDrawerToggle.ActionBarDrawerToggle(Activity,DrawerLayout,Toolbar,int,int) is   
not applicable
(argument mismatch; int cannot be converted to Toolbar)
constructor ActionBarDrawerToggle.  
<T>ActionBarDrawerToggle(Activity,Toolbar,DrawerLayout,T,int,int) is not applicable
(cannot infer type-variable(s) T
(actual and formal argument lists differ in length))
where T is a type-variable:
T extends Drawable,DrawerToggle declared in constructor   
<T>ActionBarDrawerToggle(Activity,Toolbar,DrawerLayout,T,int,int)

我不知道我哪里做错了，我看到了support/v7/widget/Toolbar和 ActionBarDrawerToggle但没有帮助

我已经喜欢了this question和 this

这是我的导入支持库

import android.os.Bundle;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.ActionBarActivity;
import android.support.v7.app.ActionBarDrawerToggle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast;

这是我的 Build.Gradle(module:app) 依赖项

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3'
compile 'com.android.support:support-v4:21.0.3'
}

这是我的 ActionBarDrawerToggle 代码

drawerListener = new ActionBarDrawerToggle(this, drawerLayout, R.drawable.ic_drawer,
            R.string.drawer_open, R.string.drawer_close) {

        @Override
        public void onDrawerOpened(View drawerView) {
            Toast.makeText(MainActivity.this, "Drawer Opened",
                    Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onDrawerClosed(View drawerView) {
            Toast.makeText(MainActivity.this, "Drawer Closed",
                    Toast.LENGTH_SHORT).show();
     }
};


drawerLayout.setDrawerListener(drawerListener);
    getSupportActionBar().setHomeButtonEnabled(true);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);

这是我的 Android Studio image

有两个 ActionBarDrawerToggle 类。 support.v4's和 support.v7's .然后，很混杂，v7的构造方法和v4的不一样。

您可以简单地通过删除第三个参数 drawerImageRes 来修复它。

drawerListener = new ActionBarDrawerToggle(
    this,
    drawerLayout,
    // R.drawable.ic_drawer, <== delete this argument
    R.string.drawer_open,
    R.string.drawer_close
    ) {

    @Override
    public void onDrawerOpened(View drawerView) {
        Toast.makeText(MainActivity.this, "Drawer Opened",
                Toast.LENGTH_SHORT).show();
    }

    @Override
    public void onDrawerClosed(View drawerView) {
        Toast.makeText(MainActivity.this, "Drawer Closed",
                Toast.LENGTH_SHORT).show();
    }
};
