Question

我正在尝试实施DrawerLayout。抽屉布局工作正常。但左上角显示的图标为android.R.id.home。但是我在ActionBarDrawerToggle中提到了我的自定义图标，如下所示：

// Getting reference to the DrawerLayout
    drawerLayout = (android.support.v4.widget.DrawerLayout) findViewById(R.id.drawer_layout);

    drawerList = (ListView) findViewById(R.id.drawer_list);



    // Getting reference to the ActionBarDrawerToggle
    drawerToggle = new ActionBarDrawerToggle(this, drawerLayout,
            **R.drawable.icon_top_menu**, R.string.drawer_open,
            R.string.drawer_close) {

        /** Called when drawer is closed */
        public void onDrawerClosed(View view) {
            super.onDrawerClosed(view);
        } 

        /** Called when a drawer is opened */
        public void onDrawerOpened(View drawerView) {
            super.onDrawerOpened(drawerView);
        }
    };

    // Setting DrawerToggle on DrawerLayout
    drawerLayout.setDrawerListener(drawerToggle);

    getActionBar().setIcon(R.drawable.icon_top_menu);
    // enabling action bar app icon and behaving it as toggle button
    getActionBar().setDisplayHomeAsUpEnabled(true);
    getActionBar().setHomeButtonEnabled(true);

有什么问题？

Answer 1

你应该检查你选择的onoptionsItem，那里应该丢失...............

如下图所示：

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}   

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will

    int id = item.getItemId();
    if (id == R.id.action_settings) {
        return true;
    }
    return super.onOptionsItemSelected(item);
}

代替'.action_settings'尝试'icon_top_menu'你的偶像.......

您应该在每个要显示图标的活动中使用图标菜单的可见性true / false ...并且请正确描述您想要做的问题。

好吧，我得到了你的问题，希望这会对你有帮助。

至于您正在使用的图标ID＆＃34; android.R.id.home＆＃34;这是＆＃39; android id＆＃39;默认情况下，代替那个使用你的图标id为R.id.home / R.id.your_icon_id希望唯一的错误为根据你的问题描述..........
