Android下Toolbar+SearchView程序崩溃闪退问题解决方法及示例
最近在用Toolbar+SearchView做搜索，整体效果想做成类微信的那种，在主页面点击搜索图标后弹出搜索页面，然后输入搜索条件进行搜索。但是在引入MenuItemCompat.setOnActionExpandListener时程序出现闪退问题。程序初步效果如下：
build.gradle主要引用的jar包配置如下，由于遇到的问题和jar版本有关所以列出来了。
dependencies {
compile fileTree(
dir
:
'libs'
,
include
: [
'*.jar'
])
testCompile
'junit:junit:4.12'
compile
'com.android.support:appcompat-v7:26.+'
compile
'com.android.support:design:26.+'
compile
'com.android.support:recyclerview-v7:26.+'
}
但是在引入MenuItemCompat.setOnActionExpandListener进行扩展事件引入时出现程序闪退，具体错误如下：

整个错误困扰了两天，查了大量资料，国内的、国外的没有个确切的解决方法，试试也都没有解决问题。后来在github下载了google官方searchview例子，例子的build.gradle配置如下： 示例源码
dependencies {
compile fileTree(
dir
:
'libs'
,
include
: [
'*.jar'
])
testCompile
'junit:junit:4.12'
compile
'com.android.support:appcompat-v7:24.0.0'
compile
'com.android.support:design:24.0.0'
compile
'com.android.support:recyclerview-v7:24.0.0'
}
在该例程中引入MenuItemCompat.setOnActionExpandListener，一切正常，程序不在闪退崩盘。这里看闪退应该是版本问题。在高版本下如何解决该问题？？？还没找到方案。
@Override
public boolean
onCreateOptionsMenu(Menu menu) {
MenuInflater menuInflater = getMenuInflater();
menuInflater.inflate(R.menu.
menu_main
, menu);
MenuItem menuItem=menu.findItem(R.id.
action_search
);
SearchView searchView = (SearchView) MenuItemCompat.
getActionView
(menuItem);
searchView.setOnQueryTextListener(
this
);
MenuItemCompat.
setOnActionExpandListener
(menuItem,
new
MenuItemCompat.OnActionExpandListener() {
@Override
public boolean
onMenuItemActionExpand(MenuItem item) {
return true
;
}
@Override
public boolean
onMenuItemActionCollapse(MenuItem item) {
return true
;
}
});
return super
.onCreateOptionsMenu(menu);
}
