Android SDK Tools Rev.17 - onClick - 找不到对应的方法处理程序 [英] Android SDK Tools Rev.17 - onClick - Corresponding method handler not found

问题描述

我将 Android SDK 工具更新至修订版 17，打开 Eclipse 后，我在问题"视图中发现了更新前不存在的新错误列表.这些错误出现在我为按钮定义了 onClick 属性的 XML 布局文件中.将鼠标悬停在错误消息示例上:

I updated Android SDK Tools to revision 17 and after I opened Eclipse I found a list of new errors in the 'Problems' view which weren't there before the update. These errors were in XML Layout files where I had defined the onClick attribute for buttons. On mouse-over the error message example:

未找到对应的方法处理程序'public void @string/timespanDefinition_btnSave_Click(android.view.View)'"

"Corresponding method handler 'public void @string/timespanDefinition_btnSave_Click(android.view.View)' not found"

返回.我已经为这个事件名称定义了相应的方法处理程序和字符串表示.这个问题的原因和解决方法是什么?

returned. I have already defined the corresponding method handler and the string representation for this event name. What is the cause and solution of this problem?

一些代码:

XML 布局

<ToggleButton
        android:id="@+id/timespanDefinition_tglVibration"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:checked="true"
        android:onClick="@string/timespanDefinition_tglVibration_Click"
        android:saveEnabled="true" />

扩展 XML 布局的活动

Activity which inflates XML Layout

public class TimespanDefinitionActivity extends Activity

{

// -- Attributes -- //

private long mRowId = -1;
private StringBuilder mBitWeekDays;
private String mTitle;

private EditText txtTitle;
private TabHost tabHost;
private TimePicker tmepkrStart;
private TimePicker tmepkrEnd;
private CheckBox[] weekDays;
private SeekBar skbrVolume;
private ToggleButton tglVibration;

// -- Class Events -- //

@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);

    setContentView(R.layout.timespan_definition);

    initializeResources();

    Bundle extras = getIntent().getExtras();

    // Get the time-span Row ID
    mRowId = (extras != null) ? extras.getLong(RVSUtilities.getDefaultPackage() + TimespanScheduleTable.KEY_ROWID)
            : -1;

    populateResources();
}

// -- User Events -- //

public void tglVibration_Click(View v)
{
    if (((ToggleButton) v).isChecked())
    {
        Vibrator vibrate = (Vibrator) getSystemService(VIBRATOR_SERVICE);
        vibrate.vibrate(1000);
    }
}

strings.xml:

strings.xml:

<string name="timespanDefinition_tglVibration_Click">tglVibration_Click</string>

注意:该应用针对的是 Android 2.3.3，特别是 Google API 版本 10

Note: The app is targeting Android 2.3.3 specifically Google API version 10

谢谢.

推荐答案

这个问题的原因和解决方法是什么?

What is the cause and solution of this problem?

原因是您使用字符串资源作为方法名称.

The cause is your use of a string resource for the method name.

解决方法是去掉字符串资源，直接把方法名放在android:onClick属性中.

The solution is to get rid of the string resource and to put the method name in the android:onClick attribute directly.

更新:如果标记没有消失，请右键单击项目，然后选择 Android 工具 > 清除 Lint 标记.

UPDATE: If the markers do not go away, right-click over the project, and choose Android Tools > Clear Lint Markers.
