java.lang.IllegalStateException: Could not find a method onStartSingleInstanceActivityClickLisenter(

错误类型：java.lang.IllegalStateException: Could not find a method onStartSingleInstanceActivityClickLisenter(View) in the activity class com.xhsc.launchmodel.StandardActivity for onClick handler on view class android.widget.Button
with id 'launmodel_satandard_btn'

1、这是采用xml布局代码中的onclick点击事件方法 android:onClick="onStartSingleInstanceActivityClickLisenter"

2、对应在我的  public class StandardActivity extends Activity 类中的

public void onStartSingleInstanceActivityClickLisenter(){
startActivity(new Intent(this, SingleInstanceActivtiy.class));
}

3、找出原因是因为少了参数(View v)public void onStartSingleInstanceActivityClickLisenter(View v){
startActivity(new Intent(this, SingleInstanceActivtiy.class));
}

所以在XML重定义按钮点击方法时，一定要在对应的类中的方法加上参数(View v)

以下是xml布局代码

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    android:orientation="vertical" >

    <TextView

        android:id="@+id/launmodel_standard_txt"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:text="StandardActivity" />

    <Button

        android:id="@+id/launmodel_satandard_btn"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:onClick="onStartSingleInstanceActivityClickLisenter"

        android:text="确定" />

</LinearLayout>

这是对应Java类代码

package com.xhsc.launchmodel;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.TextView;

import com.xhsc.layout.relativelayout.R;
/**
 * 
 * @author scxh
 *standard模式是默认的启动模式，不用为<activity>配置android:launchMode属性即可，当然也可以指定值为standard。
 */
public class StandardActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.launchmodel_standard);
((TextView)findViewById(R.id.launmodel_standard_txt)).setText("StandardActivity  current task id: "+">>>>>>>>"+this.getTaskId());

}

/*这里已遗漏参数/

public void onStartSingleInstanceActivityClickLisenter(View v){
startActivity(new Intent(this, SingleInstanceActivtiy.class));
}
}
