BadTokenException无法添加窗口中微调PopUpWindow

问题描述

我知道这里有很多类似的问题，但我不能够答案传输到我的问题（或我没有找到答案，我需要...）

在（在onOptionsItemSelected）我的动作条菜单我打开用户设置一个popupWindow。复选框，单选按钮做工精细，但如果在spinner我选项卡，将有一个致命异常：

 致命异常：主要
android.view.WindowManager $ BadTokenException：无法添加窗口 - 令牌android.view.ViewRootImpl$W@42766f00无效;是您的活动运行？
 

这是在 onOptionsItemSelected 法code：

  LayoutInflater inflaterSettings = LayoutInflater.from（背景）;
最终的LinearLayout llSettings =（的LinearLayout）inflaterSettings.inflate（R.layout.actionbar_menu_settings_popup，NULL）;
微调微调=（微调）llSettings .findViewById（R.id.spinner_action_settings_intervall_values​​）;
ArrayAdapter＆LT;＆CharSequence的GT;适配器= ArrayAdapter.createFromResource（这一点，R.array.action_settings_intervall_values​​，android.R.layout.simple_spinner_item）;
adapter.setDropDownViewResource（android.R.layout.simple_spinner_dropdown_item）;
spinner.setAdapter（适配器）;
spinner.setOnItemSelectedListener（新OnItemSelectedListener（）
{
    @覆盖
    公共无效onItemSelected（适配器视图＆LT;＆GT;母公司，观景，INT POS，长I​​D）{} TODO
    @覆盖
    公共无效onNothingSelected（适配器视图＆LT;＆GT;母公司）{// TODO}
}）;
PopupWindow弹出=新PopupWindow（背景）;
popUp.setContentView（llSettings）;
llSettings.post（新的Runnable（）
{
    @覆盖
    公共无效的run（）
    {
        popUp.showAtLocation（llSettings，Gravity.CENTER，0，0）;
        INT宽度= getResources（）getDisplayMetrics（）widthPixels。;
        INT高度= getResources（）getDisplayMetrics（）heightPixels。;
        宽度=（INT）（宽* 0.9）;
        身高=（INT）（高* 0.9）;
        popUp.update（宽度，高度）;
    }
}）;
 

我actionbar_menu_settings_popup.xml：

 ＆LT;微调
    机器人：ID =@ + ID / spinner_action_settings_intervall_values​​
    机器人：layout_width =WRAP_CONTENT
    机器人：layout_height =WRAP_CONTENT
    机器人：drawSelectorOnTop =真
    机器人：项=@阵列/ action_settings_intervall_values​​/＆GT;
 

和在string.xml：

 ＆LT;字符串数组名=action_settings_intervall_values​​＆GT;
    ＆LT;项目＆GT; 5℃/项目＆GT;
    ＆LT;项目＆GT; 15℃; /项目＆GT;
    ＆LT;项目＆GT; 30℃/项目＆GT;
    ＆LT;项目＆GT; 45℃; /项目＆GT;
    ＆LT;项目＆GT; 60℃/项目＆GT;
    ＆LT;项目＆GT; 120℃，/项目＆GT;
    ＆LT;项目＆GT; 180°; /项目＆GT;
＆LT; /字符串数组＆GT;
 

修改

做了一个登录 onOptionsItemSelected ：

  Log.i（MainActivity＃onCreateOptionsItems，背景：+背景）;
Log.i（MainActivity＃onCreateOptionsItems，getApplicationContext：+ getApplicationContext（））;
Log.i（MainActivity＃onCreateOptionsItems，这样的：这+）;
 

结果：

  10月6日至21日：40：58.185：I / MainActivity＃onCreateOptionsItems（14463）：背景：de.xy.app.activities.MainActivity@42743818
10月6日至21日：40：58.185：I / MainActivity＃onCreateOptionsItems（14463）：getApplicationContext：android.app.Application@42741d48
10月6日至21日：40：58.185：I / MainActivity＃onCreateOptionsItems（14463）：此：de.xy.app.activities.MainActivity@42743818
 

解决方案

替换行

  ArrayAdapter＆LT;＆CharSequence的GT;适配器= ArrayAdapter.createFromResource（这一点，R.array.action_settings_intervall_values​​，android.R.layout.simple_spinner_item）;
 

要

  ArrayAdapter＆LT;＆CharSequence的GT;适配器= ArrayAdapter.createFromResource（getApplicationContext（），R.array.action_settings_intervall_values​​，android.R.layout.simple_spinner_item）;
 

这会发生，主要是因为糟糕的情况下参考。

I know there are a lot of similar questions here, but I'm not able to transfer the answers to my problem (or I didn't find THE answer I need...)

In my menu on actionBar (in onOptionsItemSelected) I open a popupWindow for user settings. Checkbox and RadioButtons work fine, but if I tab on the Spinner, there will be a FATAL EXCEPTION:

FATAL EXCEPTION: main
android.view.WindowManager$BadTokenException: Unable to add window -- token android.view.ViewRootImpl$W@42766f00 is not valid; is your activity running?

This is the code in the onOptionsItemSelected Method:

LayoutInflater inflaterSettings = LayoutInflater.from(context);
final LinearLayout llSettings = (LinearLayout) inflaterSettings.inflate(R.layout.actionbar_menu_settings_popup, null);
Spinner spinner = (Spinner) llSettings .findViewById(R.id.spinner_action_settings_intervall_values);
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this, R.array.action_settings_intervall_values, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
spinner.setOnItemSelectedListener(new OnItemSelectedListener()
{
    @Override
    public void onItemSelected(AdapterView<?> parent, View view, int pos, long id){ TODO}
    @Override
    public void onNothingSelected(AdapterView<?> parent) { // TODO }
});
PopupWindow popUp = new PopupWindow(context);
popUp.setContentView(llSettings);
llSettings.post(new Runnable()
{
    @Override
    public void run()
    {
        popUp.showAtLocation(llSettings, Gravity.CENTER, 0, 0);
        int width = getResources().getDisplayMetrics().widthPixels;
        int height = getResources().getDisplayMetrics().heightPixels;
        width = (int) (width * 0.9);
        height = (int) (height * 0.9);
        popUp.update(width, height);
    }
});

My actionbar_menu_settings_popup.xml:

<Spinner
    android:id="@+id/spinner_action_settings_intervall_values"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:drawSelectorOnTop="true"
    android:entries="@array/action_settings_intervall_values" />

and in string.xml:

<string-array name="action_settings_intervall_values">
    <item>5</item>
    <item>15</item>
    <item>30</item>
    <item>45</item>
    <item>60</item>
    <item>120</item>
    <item>180</item>
</string-array>

EDIT

Made a Log in onOptionsItemSelected:

Log.i("MainActivity#onCreateOptionsItems", "context: " + context);
Log.i("MainActivity#onCreateOptionsItems", "getApplicationContext: " + getApplicationContext());
Log.i("MainActivity#onCreateOptionsItems", "this: " + this);

result:

06-21 10:40:58.185: I/MainActivity#onCreateOptionsItems(14463): context: de.xy.app.activities.MainActivity@42743818
06-21 10:40:58.185: I/MainActivity#onCreateOptionsItems(14463): getApplicationContext: android.app.Application@42741d48
06-21 10:40:58.185: I/MainActivity#onCreateOptionsItems(14463): this: de.xy.app.activities.MainActivity@42743818

解决方案

Replace the line

ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this, R.array.action_settings_intervall_values, android.R.layout.simple_spinner_item);

To

ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(getApplicationContext(), R.array.action_settings_intervall_values, android.R.layout.simple_spinner_item);

This occurs mostly because of bad context reference.
