android - ActionBarDrawerToggle 的 setToolbarNavigationClickListener 不起作用

Question

我正在尝试使用自定义点击事件实现 ActionBarDrawerToggle，但它似乎不起作用。

我像这样创建了新的 ActionBarDrawerToggle:

drawerToggle = new ActionBarDrawerToggle(activity, drawer, R.string.open, R.string.close);

像这样设置 ActionBar:

getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);

像这样添加自定义监听器:

drawerToggle.setDrawerIndicatorEnabled(false);
drawerToggle.setToolbarNavigationClickListener(myListener);

结果:永远不会触发点击事件。

如何将自定义点击事件附加到 ActionBarDrawerToggle？根据谷歌的文档，关键只有这个:drawerToggle.setDrawerIndicatorEnabled(false);。谢谢。

我创建了一个应用程序作为示例。请看下面。请特别注意 MainActivity.java 中的三个注释，它们描述了您应该如何实现您的监听器。

图片千余字:

• Default behaviour
• Custom behaviour

MainActivity.java

import android.content.res.Configuration;
import android.os.Bundle;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.ActionBarDrawerToggle;
import android.support.v7.app.AppCompatActivity;
import android.view.MenuItem;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {

    private ActionBarDrawerToggle mDrawerToggle;
    private DrawerLayout mDrawerLayout;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);

        getSupportActionBar().setDisplayHomeAsUpEnabled(true);

        mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.string.open, R.string.close);
        // 1.
        // if you want the default behaviour for ActionBarDrawerToggle
        // uncomment the first line below and comment out the second one
//        mDrawerLayout.setDrawerListener(mDrawerToggle);
        mDrawerToggle.setDrawerIndicatorEnabled(false);
    }

    @Override
    protected void onPostCreate(Bundle savedInstanceState) {
        super.onPostCreate(savedInstanceState);
        mDrawerToggle.syncState();
    }

    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        mDrawerToggle.onConfigurationChanged(newConfig);
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // 2.
        // the default behaviour for ActionBarDrawerToggle
        if (mDrawerToggle.onOptionsItemSelected(item)) {
            return true;
        }

        int id = item.getItemId();

        if (id == android.R.id.home) {
            // 3.
            // here you can define your custom click listener / onClick method
            // for ActionBarDrawerToggle
            String customClick = getResources().getString(R.string.custom_click_event);
            Toast.makeText(this, customClick, Toast.LENGTH_LONG).show();
            return true;
        }

        return super.onOptionsItemSelected(item);
    }
}
