How animate Burger to Arrow with Appcompat v7 21, Toolbar and DrawerLayout
提问by user2298916
I am using the android.support.v7.widget.Toolbar with a android.support.v4.widget.DrawerLayout. It works fine, the Burger icon is shown when the Navigation Drawer is closed, and the Arrow icon is shown when the Drawer is open. I want to disable the drawer and animate the Burger icon into Arrow on some event in the app. I have tried to set the lock mode to closed, but the v7.app.ActionBarDrawerToggle is still showing the Burger and it opens the Drawer.
我正在使用带有 android.support.v4.widget.DrawerLayout 的 android.support.v7.widget.Toolbar。它工作正常，当导航抽屉关闭时显示汉堡图标，当抽屉打开时显示箭头图标。我想在应用程序中的某个事件中禁用抽屉并将 Burger 图标设置为 Arrow 动画。我试图将锁定模式设置为关闭，但 v7.app.ActionBarDrawerToggle 仍然显示 Burger 并打开 Drawer。
mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);
mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);
Any ideas? Thanks!
有任何想法吗？谢谢！
Update:
更新：
No I can change the state of the icon and I can enable/disable the drawer, but the animations are not working with this approach:
不，我可以更改图标的状态，并且可以启用/禁用抽屉，但是动画不适用于这种方法：
@Override
protected void onCreate(Bundle savedInstanceState) {
...
Toolbar toolbar = (Toolbar) findViewById(R.id.application_toolbar);
setSupportActionBar(toolbar);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawerLayout);
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.string.string1, R.string.string2) {
public void onDrawerClosed(View view) {
super.onDrawerClosed(view);
}
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
}
};
//mDrawerLayout.setDrawerListener(mDrawerToggle); // not needed
...
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
if (mDrawerLayout.getDrawerLockMode(GravityCompat.START) == LOCK_MODE_UNLOCKED) {
showDrawer();
} else {
handleBackButtonPress(); // On this stage the home button is a <-
}
}
...
}
private void setDrawerState(boolean isEnabled) {
if (isEnabled) {
mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED);
mDrawerToggle.onDrawerStateChanged(DrawerLayout.LOCK_MODE_UNLOCKED);
mDrawerToggle.syncState();
} else {
mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);
mDrawerToggle.onDrawerStateChanged(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);
mDrawerToggle.syncState();
}
}
The drawer comes on the top of the Toolbar.
抽屉位于工具栏的顶部。

The essential part is the following:
主要部分如下：
<style name="AppTheme" parent="Theme.AppCompat.Light">
<item name="drawerArrowStyle">@style/DrawerArrowStyle</item>
</style>
<style name="DrawerArrowStyle" parent="Widget.AppCompat.DrawerArrowToggle">
<item name="spinBars">true</item>
<item name="color">@android:color/white</item>
</style>

drawerLayout.setDrawerListener(actionBarDrawerToggle);
//Set the custom toolbar
if (toolbar != null){
setSupportActionBar(toolbar);
}
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
actionBarDrawerToggle.syncState();
