当我在手机上运行我的应用程序时，出现错误：

不幸的是，当我按下切换按钮时，应用程序 gemdata 已停止

我不知道出了什么问题，有人可以帮忙吗？

感谢 Wesley，我发现问题发生了，因为我在我的 xml 文件中设置了 Onclick 属性

我的代码如下所示：

package dk.SimonPedersen.gemdata2;

import android.app.Activity;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.util.Log;
import android.widget.Button;
import android.widget.CompoundButton;
import android.widget.EditText;
import android.widget.ToggleButton;

public class MainActivity extends Activity {
public static final String GEMFFS = "dk.SimonPedersen.GEMFFS";

protected static final boolean Sex = false;

SharedPreferences ada;
SharedPreferences.Editor editor;
Button btnGem;
ToggleButton tbKon;
EditText etVaegt;
Double sex;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    ada = getSharedPreferences(GEMFFS, 0);
    editor = ada.edit();

    btnGem = (Button) findViewById (R.id.btnGem);
    tbKon = (ToggleButton) findViewById (R.id.tbKon);
    etVaegt = (EditText) findViewById (R.id.etVaegt);

    tbKon.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
            if (isChecked) {
                sex=0.7d;
            } else {
                sex=0.6d;
            }    
        }
    });
}   
}

这是我在 logcat 中遇到的错误：

检查您的 xml 文件中是否有 ID 为 tbKon 的 ToggleButton。

我想你已经在 xml 文件中设置了 onClick 属性，看起来像 onClick="onToggleClicked"
