我使用Android 5.0中的新工具栏实现了一个基本的ActionBarDrawerToggle。
但是,我无法弄清楚如何更改提供的默认汉堡包图标。 从android文档中可以看出"给定的Activity将链接到指定的DrawerLayout,工具栏的导航图标将被设置为自定义drawable ...这个drawable在抽屉关闭时显示汉堡图标抽屉打开时的箭头。当抽屉打开时,它会在这两种状态之间激活。"
我目前使用以下代码正常工作,但是我想用我自己的drawable替换默认提供的汉堡包。
这是我目前的代码:
MainActivity.java
@InjectView(R.id.main_activity_toolbar)
Toolbar mToolbar;
@InjectView(R.id.main_activity_drawer_layout)
DrawerLayout mDrawerLayout;
@Override
protected void onCreate(Bundle savedInstanceState) {
setContentView(R.layout.main_activity);
super.onCreate(savedInstanceState);
setSupportActionBar(mToolbar);
mToolbar.setNavigationIcon(R.drawable.navigation);
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, mToolbar, R.string.drawer_open, R.string.drawer_close) {
public void onDrawerClosed(View view) {
super.onDrawerClosed(view);
invalidateOptionsMenu();
}
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
invalidateOptionsMenu();
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
}
这一行:
mToolbar.setNavigationIcon(R.drawable.navigation);
似乎不起作用。
这可能吗?谢谢!

这两行代码对我有用:
DataRow newRow = ds.Tables[tableToAdd].Rows.Add();
newRow["partno"] = ds.Tables[tableToAdd].Rows[i - 1]["partno"];
然后打电话给:
String string="I would loved to be the part of cricket team"

您可以将工具栏用作独立模式,这意味着您不使用工具栏作为 ActionBarDrawerToggle 构造函数的一部分,您可以使用以下代码实现这一点:
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, null,
R.drawable.appbar, R.drawable.appbar)
(注意工具栏实例未如何发送到ActionBarDrawerToggle构造函数)
此外,您应手动充气菜单
mToolbar = (Toolbar) findViewById(R.id.nav_toolbar);
mToolbar.inflateMenu(R.menu.base);
删除 setSupportActionBar(mToolbar); 代码行。
当然,您必须自己处理导航点击:
mToolbar.setOnMenuItemClickListener(new OnMenuItemClickListener() ...
然后,您可以这样打开您的抽屉:
drawerButton = (BadgeDrawerButton) findViewById(R.id.badge_drawer_button);
drawerButton.setOnClickListener(
new View.OnClickListener() {
@Override
public void onClick(View v) {
mDrawerLayout.openDrawer(Gravity.LEFT);
}
});
希望这可能会有所帮助。

我的解决方案是继承ActionBarDrawerToggle。
public class MyActionBarDrawerToggle extends android.support.v7.app.ActionBarDrawerToggle {
public MyActionBarDrawerToggle(Activity activity, final DrawerLayout drawerLayout, Toolbar toolbar, int openDrawerContentDescRes, int closeDrawerContentDescRes) {
super(activity, drawerLayout, toolbar, openDrawerContentDescRes, closeDrawerContentDescRes);
setHomeAsUpIndicator(R.drawable.drawer_toggle);
setDrawerIndicatorEnabled(false);
setToolbarNavigationClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
drawerLayout.openDrawer(Gravity.LEFT);
}
});
}
}

ActionBarDrawerToggle的默认菜单是DrawerArrowDrawable。
您可以将其子类化以添加自定义功能,例如徽章,如下所示:
<my-textarea @keyup="update()" @change="somethingElse()"></my-textarea>
用法:
<li>

对我有用的是我只需要拨打toolbar.setNavigationIcon(R.drawable.ic_camera_alt_24dp);
在onCreate结束时,或者至少在mDrawerToggle = new ActionBarDrawerToggle...
之后

对于v7支持库 - 您可以创建自己的DrawerArrowDrawable表示。
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close) {
public void onDrawerClosed(View view) {
supportInvalidateOptionsMenu();
}
public void onDrawerOpened(View drawerView) {
supportInvalidateOptionsMenu();
}
};
mDrawerToggle.setDrawerIndicatorEnabled(true);
DrawerArrowDrawable drawerArrowDrawable = new DrawerArrowDrawable(this);
drawerArrowDrawable.setAlpha(1);
drawerArrowDrawable.setSpinEnabled(false);
drawerArrowDrawable.setDirection(DrawerArrowDrawable.ARROW_DIRECTION_LEFT);
drawerArrowDrawable.setColor(Color.BLACK);
mDrawerToggle.setDrawerArrowDrawable(drawerArrowDrawable);

截至2018年1月,这是一个有效的解决方案(至少对我而言):
//setSupportActionBar(toolbar)
val toggle = ActionBarDrawerToggle(this, drawer_layout, null, R.string.navigation_drawer_open, R.string.navigation_drawer_close)
toolbar.inflateMenu(R.menu.menu_main)
toolbar.setNavigationIcon(R.drawable.ic_menu)
toolbar.setNavigationOnClickListener {
drawer_layout.openDrawer(Gravity.START)
}
toolbar.setOnMenuItemClickListener {
true
}
drawer_layout.addDrawerListener(toggle)
toggle.syncState()
nav_view.setNavigationItemSelectedListener(this)
需要关注的事项:
setSupportActionBar
应该被注释掉ActionBarDrawerToggle
未提及toolbar
onCreateOptionsMenu
和onOptionsItemSelected
将无效。toggle.syncState()

以下是我最终能够让我的工作方式。
private Toolbar toolbar;
toolbar = (Toolbar) findViewById(R.id.toolbar);
if (toolbar != null) {
setSupportActionBar(toolbar);
toolbar.setNavigationIcon(R.drawable.ic_drawer);
mDrawerToggle = new ActionBarDrawerToggle(this,
mDrawerLayout,
toolbar,
R.string.drawer_open,
R.string.drawer_close) {
/** Called when a drawer has settled in a completely closed state. */
public void onDrawerClosed(View view) {
super.onDrawerClosed(view);
}
/** Called when a drawer has settled in a completely open state. */
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
}
};
// Set the drawer toggle as the DrawerListener
mDrawerLayout.setDrawerListener(mDrawerToggle);
mDrawerToggle.syncState();
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
}
原来是
mDrawerToggle.syncState();
最终让一切顺利。

我认为建议在syncState()
生命周期方法中调用onPostCreate(...)
。
@Override
public void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
mDrawerToggle.syncState();
}

drawer.setDrawerListener(toggle);
toggle.syncState();
toolbar.setNavigationIcon(R.drawable.ic_action_name);
