我正在尝试使用自定义单击事件来实现ActionBarDrawerToggle,但似乎无法正常工作。

我创建了这样的新ActionBarDrawerToggle:

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


像这样设置ActionBar:

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


添加了自定义侦听器,如下所示:

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


结果:永远不会触发Click事件。

如何将自定义单击事件附加到ActionBarDrawerToggle?根据Google的文档,关键仅在于此:drawerToggle.setDrawerIndicatorEnabled(false);。谢谢。

最佳答案

我以一个应用程序为例。请参阅下面。请特别注意MainActivity.java中的三个注释,这些注释描述了应如何实现侦听器。
图片超过一千个字:


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);
    }
}

关于android - ActionBarDrawerToggle的setToolbarNavigationClickListener不起作用,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/33636104/
