我尝试过,但只在单击2次后才传递到该方法,我将项目文件放在网上:),很抱歉使用xml,因为我是意大利人,xml资源中的所有写入都是意大利语,但只有4次写入:)

我听从了你的建议,但喷气机不起作用,你能试试我的代码吗?:) 在onCreateOptions菜单(菜单菜单菜单)中,添加以下行:
// This will add the back arrow to your action bar.
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
在选项ItemSelected()中添加以下内容:
// Respond to the action bar's Up/Home button
if (item.getItemId() == android.R.id.home) {
hideSoftKeyboard(this);
// finish(), NavUtils.navigateUpFromSameTask(activity) or something like that
}
使用隐藏键盘的方法:
public static void hideSoftKeyboard(Activity activity) {
InputMethodManager inputMethodManager = (InputMethodManager) activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
inputMethodManager.hideSoftInputFromWindow(activity.getCurrentFocus().getWindowToken(), 0);
}
覆盖活动的
onOptionsItemSelected
方法,以拦截点击android.R.id.home
@Override
public boolean onOptionsItemSelected(MenuItem item) {
if (item.getItemId() == android.R.id.home) {
searchView.postDelayed(new Runnable() {
@Override
public void run() {
InputMethodManager imm = (InputMethodManager) this.getSystemService(Context.INPUT_METHOD_SERVICE);`enter code here`
imm.hideSoftInputFromWindow(searchView.getWindowToken(), 0);
}
}, 300);
return true;
}
return super.onOptionsItemSelected(item);
}
我已经编辑了我的答案。您需要使用我的答案中的方法将返回箭头添加到acion栏。然后,所有按下操作将自动发送到OnOptions ItemSelected()。您不应使用“NavigationOnClickListener”和“OnOptions ItemSelected”。删除侦听器,使用“OnOptions ItemSelected”一切都会正常工作
// Respond to the action bar's Up/Home button
if (item.getItemId() == android.R.id.home) {
hideSoftKeyboard(this);
// finish(), NavUtils.navigateUpFromSameTask(activity) or something like that
}
public static void hideSoftKeyboard(Activity activity) {
InputMethodManager inputMethodManager = (InputMethodManager) activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
inputMethodManager.hideSoftInputFromWindow(activity.getCurrentFocus().getWindowToken(), 0);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
if (item.getItemId() == android.R.id.home) {
searchView.postDelayed(new Runnable() {
@Override
public void run() {
InputMethodManager imm = (InputMethodManager) this.getSystemService(Context.INPUT_METHOD_SERVICE);`enter code here`
imm.hideSoftInputFromWindow(searchView.getWindowToken(), 0);
}
}, 300);
return true;
}
return super.onOptionsItemSelected(item);
}
