java无法为安卓执行方法：安卓中的onClick

1 周，3 日 Questions & Answers 648

我似乎无法弄清这件事的真相。使用ApachePOI读取excel文件。似乎在出错。使应用程序强制关闭

java.lang.IllegalStateException: Could not execute method for 安卓:onClick

Full error output

我的XML 安卓:onClick id与我的方法侦听器具有相同的名称：

 <Button
    安卓:text="OK"
    安卓:id="@+id/submitOK"
    安卓:textAlignment="center"
    安卓:textAppearance="@style/TextAppearance.AppCompat.Caption"
    安卓:textSize="12sp"
    安卓:background="@drawable/round_button"
    安卓:gravity="center_vertical|center_horizontal"
    安卓:textColor="#fff"
    安卓:layout_alignTop="@+id/setName"
    安卓:layout_toRightOf="@+id/setName"
    安卓:layout_marginLeft="5dp"
    安卓:layout_width="30dp"
    安卓:layout_height="30dp"
    安卓:layout_alignBottom="@+id/setName"
    **安卓:onClick="inRoster"**
    安卓:visibility="gone"
/>

public void inRoster(View v) throws IOException {
    if (checkValidinFile()) {
        // Send to a new page that lists your shifts, what time you want your alarms
        // and what time you want messages to be sent
        // What time do you want to send the messages?
        // What time do you want your alarms to be?
        // Do all alarm and message sending bs
    } else {
        // Display a toast message saying name not found
        // Clear contents of the editbox for the name for user to re enter
        CharSequence text = "Name not found in Roster!";
        setName.setText("");
        int duration = Toast.LENGTH_SHORT;
        Toast.makeText(this, text, duration).show();
    }
}

这似乎是这种方法出现错误的地方，但我不明白为什么

public boolean checkValidinFile() throws IOException {
    String nameToMatch = setName.getText().toString().toLowerCase();

    try {
        InputStream ExcelFileToRead = new FileInputStream(roster);
        XSSFWorkbook wb = new XSSFWorkbook(ExcelFileToRead);
        XSSFSheet sheet = wb.getSheetAt(0);

        Iterator<Row> iterator = sheet.iterator();

        while (iterator.hasNext()) {

            Row currentRow = iterator.next();
            Iterator<Cell> cellIterator = currentRow.iterator();
            while (cellIterator.hasNext()) {

                Cell currentCell = cellIterator.next();
                System.out.println(currentCell.toString() + " ");
            }
        }
        System.out.println();

        wb.close();
        ExcelFileToRead.close();
    }
    catch (IOException e) {
        e.printStackTrace();
    }
    return true;
}

“SetName”在类的顶部全局定义，没有实例化，然后在onCreate中定义为：

setName = (EditText) findViewById(R.id.setName);

非常感谢您的帮助，请告诉我您还需要哪些其他信息，我还遇到了一些关于I/art拒绝重新初始化以前失败的类的其他问题。如果您认为这两个问题可能有关联，请参阅下面的链接
