Question

我想获取最近拨打的电话的详细信息，即最后一个电话号码，日期，时间，持续时间等。我已经编写了代码，但第一次我的应用程序崩溃，下次显示第二次拨打电话的详细信息。

private class PhoneCallListener extends PhoneStateListener {

        private boolean isPhoneCalling = false;

        String LOG_TAG = "Test";


        @Override
        public void onCallStateChanged(int state, String incomingNumber) {

            if (TelephonyManager.CALL_STATE_RINGING == state) {
                Log.i(LOG_TAG, "RINGING, number: " + incomingNumber);
            }

        if (TelephonyManager.CALL_STATE_OFFHOOK == state) {
            Log.i(LOG_TAG, "OFFHOOK");
            isPhoneCalling = true;
            Log.i("Test", "OFFHOOK" + isPhoneCalling );
        }

        if (TelephonyManager.CALL_STATE_IDLE == state) {
            // run when class initial and phone call ended, need detect flag from CALL_STATE_OFFHOOK
            Log.i(LOG_TAG, "IDLE");

            Log.i("Test", "IDLE" + isPhoneCalling);
            if (isPhoneCalling) {   
                Log.i(LOG_TAG, "restart app");

                isPhoneCalling = false;
                Cursor c = ContactMainActivity.this.getContentResolver().query(CallLog.Calls.CONTENT_URI, null, null, null, CallLog.Calls.DATE + " DESC");
                LayoutInflater layoutInflater = (LayoutInflater)getSystemService(LAYOUT_INFLATER_SERVICE);
                View layout = layoutInflater.inflate(R.layout.toast_layout, null);
                final String name;
                final String number;
                String duration, date;

                if (c != null) {
                    if (c.moveToPosition(0)) {
                        name= c.getString(c.getColumnIndex(Calls.CACHED_NAME));
                        number= c.getString(c.getColumnIndex(Calls.NUMBER));
                        duration= c.getString(c.getColumnIndex(Calls.DURATION));
                        Date date1=  new Date(Long.valueOf(c.getString(c.getColumnIndex(Calls.DATE))));
                        String Temp=date1.toString(); 
}
}

我在一个对话框中显示所有信息，以便在该对话框中显示。它显示错误但只是第一次

logcat的：
