android - Timepicker 似乎在使用 Android 版本 6.0.1 的三星设备上使我的应用程序崩溃

标签 android nullpointerexception crash timepicker

我正面临一个非常烦人的情况。我正在尝试使用 DatePicker 和 TimePicker 显示警报对话框。它适用于除某些三星设备之外的所有设备(根据我收到的崩溃报告，它们都是 Android 版本 6.0.1)。

这是崩溃报告:

CUSTOM_DATA=

ANDROID_VERSION=6.0.1
APP_VERSION_NAME=3.1.0

这是我的代码:
public void askTimestamp(final String transaction_type, final String item_name, final int integerItems, final EditText item_count, final int newItemCount, final TextView textBox_count)
{
    final AlertDialog.Builder dialog = new AlertDialog.Builder(this);
    dialog.setTitle("Enter Transaction Details");
    View view = getLayoutInflater().inflate(R.layout.dialog_date_time, null);
    final CustomDatePicker datePicker = (CustomDatePicker) view.findViewById(R.id.datePicker);
    final TimePicker timePicker = (TimePicker) view.findViewById(R.id.timePicker);
    dialog.setView(view);
    dialog.setPositiveButton(getString(R.string.done), new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int id) {
            String day = "";
            String month = "";
            String year = "";
            String hours = "";
            String minutes = "";
            String seconds = "00";
            day = datePicker.getDayOfMonth() + "";
            if (day.length() == 1)
            {
                day = "0" + day;
            }
            int actualMonth = datePicker.getMonth() + 1;
            month = actualMonth + "";
            if (month.length() == 1)
            {
                month = "0" + month;
            }
            year = datePicker.getYear() + "";
            if (year.length() == 3)
            {
                year = "0" + year;
            }
            else if(year.length() == 2)
            {
                year = "00" + year;
            }
            else if(year.length() == 1)
            {
                year = "000" + year;
            }
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M)
            {
                hours = timePicker.getHour() + "";
                minutes = timePicker.getMinute() + "";
            }
            else
            {
                hours = timePicker.getCurrentHour() + "";
                minutes = timePicker.getCurrentMinute() + "";
            }
            if (hours.length() == 1)
            {
                hours = "0" + hours;
            }
            if (minutes.length() == 1)
            {
                minutes = "0" + minutes;
            }
            String dateTime = year + "-" + month + "-" + day + " " + hours + ":" + minutes + ":" + seconds;
            dbHelper.updateItem(item_name, newItemCount);
            dbHelper.createTransaction(transaction_type, item_name, integerItems, dateTime);
            if (transaction_type.equals("add"))
            {
                Toast.makeText(MyApp.getContext(), getString(R.string.transaction_adding) + " " + item_name.trim() + " " + getString(R.string.succeeded) + "!", Toast.LENGTH_SHORT).show();
            }
            else
            {
                Toast.makeText(MyApp.getContext(), getString(R.string.transaction_removing) + " " + item_name.trim() + " " + getString(R.string.succeeded) + "!", Toast.LENGTH_SHORT).show();
            }
            item_count.setText("");
            textBox_count.setText(newItemCount + "");
            dialog.cancel();
        }
    });
    dialog.setNegativeButton(getString(R.string.cancel), new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id)
                {
                    // User cancelled the dialog
                    dialog.dismiss();
                }
    });
    AlertDialog dialog_created = dialog.create();
    if (!this.isFinishing())
    {
        dialog_created.show();
    }
}

这是我试图膨胀的布局:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">

    android:id="@+id/linearLayout1"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical" >

    <ankit.inventory.ankitarora.inventorymanagementsimple.CustomDatePicker
        android:id="@+id/datePicker"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:scrollbars="vertical"
        android:theme="@android:style/Theme.Holo.Light" >
    </ankit.inventory.ankitarora.inventorymanagementsimple.CustomDatePicker>

    <TimePicker
        android:id="@+id/timePicker"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/datePicker"
        android:scrollbars="vertical"
        android:theme="@android:style/Theme.Holo.Light" >
    </TimePicker>

</RelativeLayout>

请帮忙!

PS:我在我的应用程序中使用 ACRA 崩溃报告系统收到了这个崩溃报告。

最佳答案

奇怪的是，我最近才开始看到这种崩溃。我尝试的解决方法是继承 TimePicker 并捕获崩溃。不幸的是，我无法访问任何受影响的设备(Galaxy J1、Galaxy J3、Galaxy On7 Pro、Galaxy A7)来验证这种方法。

class TimePicker(context: Context, attrs: AttributeSet?) : android.widget.TimePicker(context, attrs) {
    override fun onRtlPropertiesChanged(layoutDirection: Int) {
        try {
            super.onRtlPropertiesChanged(layoutDirection)
        } catch (e: Exception) {
            Timber.e(e)
        }
    }
}
