大家好我正在开发一个使用旧导航抽屉方法的应用程序。当我将'com.android.support:appcompat-v7:23.1.1'更新为'com.android.support:appcompat-v7:23.4.0'我的导航抽屉未打开时。
我调试了代码并查找了已弃用的项目，但找不到任何错误代码或消息。一切都很完美，但导航抽屉没有打开。这是我的代码。提前致谢。

抽屉被锁定。
更改
<?php
$args = array( 'numberposts' => '1', 'offset' => '0', 'orderby' => 'post_date', 'order' => 'DESC', 'post_status' => 'publish' );
$recent_posts = wp_get_recent_posts( $args );
$home = home_url( '/' );
$homeURL = esc_url( $home );
$before = '<a href="';
$after = '">dive in</a>';
foreach( $recent_posts as $recent ){
$slug = basename( get_permalink($recent["ID"]) );
// if post is audio
if ( has_category('audioz', $recent["ID"]) ) {

这是我自己找到的最新解决方案。 drawerOpenCloseControl是布尔标志。我控制的是真还是假。然后手动打开和关闭。
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
if(drawerOpenCloseControl){
mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_OPEN);
drawerOpenCloseControl = false;
}
else{
mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);
drawerOpenCloseControl = true;
}
break;
}
return super.onOptionsItemSelected(item);
}
