单击时,DatePicker在我的设备上崩溃(使用个人应用程序)

Question

编辑:我检查过该问题仅在手机设置为"法语"时出现.

我目前正在构建自己的应用程序,在手机上使用DatePicker小部件时遇到问题(调试模式手机:三星S5).

错误收集是:java.util.IllegalFormatConversionException

我添加了有关logcat中收集的问题的更多详细信息:

这是我的DialogFragment代码:

public class DatePFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener {

    DatePicker dp;
    OnDatePickedListener mCallback;
    Integer mLayoutId = null;

    // Interface definition
    public interface OnDatePickedListener {
        public void onDatePicked(int textId, int year, int month, int day);
    }

    // make sure the Activity implement the OnDatePickedListener
    public void onAttach(Activity activity) {
        super.onAttach(activity);

        try {
            mCallback = (OnDatePickedListener)activity;
        }
        catch (final ClassCastException e) {
            throw new ClassCastException(activity.toString() + " must implement OnDatePickedListener");
        }
    }

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState){
        mCallback = (OnDatePickedListener)getActivity();

        Calendar cal = Calendar.getInstance();
        Bundle bundle = this.getArguments();
        mLayoutId = bundle.getInt("layoutId");
        int year = cal.get(Calendar.YEAR);
        int month = cal.get(Calendar.MONTH);
        int day = cal.get(Calendar.DAY_OF_MONTH);

        View view = getActivity().getLayoutInflater().inflate(R.layout.datepfragment, null);

        dp = (DatePicker) view.findViewById(R.id.datePicker);

        // Create a new instance of DatePickerDialog and return it
        return new DatePickerDialog(getActivity(),this,year, month, day);
    }

    @Override
    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
        if (mCallback != null) {
            // Use the date chosen by the user.

            mCallback.onDatePicked(mLayoutId, year, monthOfYear+1, dayOfMonth);
        }
    }
}

这是相关的xml布局:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent">

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="@string/txtDPTitle"
        android:id="@+id/txtDPTitle"
        android:layout_gravity="center_horizontal"
        android:gravity="center"
        android:layout_alignParentTop="true"
        android:layout_alignParentStart="true"
        android:layout_marginTop="35dp" />

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/btnDPValidate"
        android:id="@+id/btnDPValidate"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true"
        android:layout_marginBottom="35dp" />

    <DatePicker
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/datePicker"
        android:layout_gravity="center_horizontal"
        android:layout_marginLeft="0dp"
        android:datePickerMode="spinner"
        android:calendarViewShown="false"
        android:layout_centerVertical="true"
        android:layout_centerHorizontal="true" />

</RelativeLayout>

事实是我有两种问题(导致应用程序崩溃):

1. 当我进入我的应用程序并直接转到DatePicker小部件时,日历会正确显示,一旦我选择了一天(我说一天,因为例如更改年份没有问题),应用程序崩溃了.
2. 如果我继续其他功能点击以显示DatePicker,它会直接崩溃.

我看到其他线程如:DatePicker在三星与android 5.0崩溃

在这个线程中我没有得到足够的信息,因为给定的解决方案只允许显示日历的微调器视图,而且显示的微调器没有居中并呈现为我的(直接放在屏幕的顶部).

如果您需要更多详细信息,请询问我.

谢谢.亚历克斯.

Answer 1

这是他们的Lollipop UI实现中的三星错误.它会影响Galaxy S4,S5,Note 3以及更多设备.对我们来说,它发生在de_DE和de_AT语言上,但它似乎是一个影响多种语言的问题.

我通过强制三星设备使用Holo主题作为日期选择器来修复它.在我们的DatePickerFragment中:

@NonNull
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    /* calendar code here */

    Context context = getActivity();
    if (isBrokenSamsungDevice()) {
        context = new ContextThemeWrapper(getActivity(), android.R.style.Theme_Holo_Light_Dialog);
    }
    return new DatePickerDialog(context, this, year, month, day);
}

private static boolean isBrokenSamsungDevice() {
    return (Build.MANUFACTURER.equalsIgnoreCase("samsung")
            && isBetweenAndroidVersions(
            Build.VERSION_CODES.LOLLIPOP,
            Build.VERSION_CODES.LOLLIPOP_MR1));
}

private static boolean isBetweenAndroidVersions(int min, int max) {
    return Build.VERSION.SDK_INT >= min && Build.VERSION.SDK_INT <= max;
}

感谢三星,他们的用户将无法获得精美的材料设计日期选择器.

Answer 2

我有一个可能的FIX PATCH,实际上让用户继续使用Lollipop库.

我只能通过在带有Android 5.0.1法语的S4上启用TalkBack来重现崩溃,似乎三星将整个日期传递给用于可访问性的项目选择字符串而不是日期编号.

基于@mreichelt包装上下文的解决方案,我们可以覆盖getString(id,args)函数并实际修复问题.

context = new ContextWrapper(getActivity()) {

    private Resources wrappedResources;

    @Override
    public Resources getResources() {
        Resources r = super.getResources();
        if(wrappedResources == null) {
            wrappedResources = new Resources(r.getAssets(), r.getDisplayMetrics(), r.getConfiguration()) {
                @NonNull
                @Override
                public String getString(int id, Object... formatArgs) throws NotFoundException {
                    try {
                        return super.getString(id, formatArgs);
                    } catch (IllegalFormatConversionException ifce) {
                        Log.e("DatePickerDialogFix", "IllegalFormatConversionException Fixed!", ifce);
                        String template = super.getString(id);
                        template = template.replaceAll("%" + ifce.getConversion(), "%s");
                        return String.format(getConfiguration().locale, template, formatArgs);
                    }
                }
            };
        }
        return wrappedResources;
    }
};

因此,如果我们将此上下文提供给DatePickerDialog构造函数,它将解决该问题.

更新: 当页面包含日期输入字段时,此问题也出现在webview中,我发现解决这两个问题(对话框和webview)的最佳方法是覆盖Activity getResources函数,如下所示:

@Override
public Resources getResources() {
    if (wrappedResources == null) {
        wrappedResources = wrapResourcesFixDateDialogCrash(super.getResources());
    }
    return wrappedResources;
}

public Resources wrapResourcesFixDateDialogCrash(Resources r) {
    return new Resources(r.getAssets(), r.getDisplayMetrics(), r.getConfiguration()) {
        @NonNull
        @Override
        public String getString(int id, Object... formatArgs) throws NotFoundException {
            try {
                return super.getString(id, formatArgs);
            } catch (IllegalFormatConversionException ifce) {
                Log.i("DatePickerDialogFix", "IllegalFormatConversionException Fixed!", ifce);
                String template = super.getString(id);
                template = template.replaceAll("%" + ifce.getConversion(), "%s");
                return String.format(getConfiguration().locale, template, formatArgs);
            }
        }
    };
}

注意:该解决方案包含缓存资源 - 这意味着如果您在应用程序中有事件更改资源(如语言更改),则可能需要更新缓存资源.
