Question

android页面跳转到空白页？？？

这是部分代码
TaskMangerActivity.java:
public void enterSetting(View view){
Intent intent = new Intent(this,TaskSettingActivity.class);
startActivity(intent);

//startActivityForResult(intent, 0);

}
protected void onActivityResult(int requestCode, int resultCode,Intent data) {
adapter.notifyDataSetChanged();
super.onActivityResult(requestCode, resultCode, data);
}
TaskSettingActivity.java:
package com.example.android_demo2;

import android.app.Activity;
import android.content.SharedPreferences;
import android.content.SharedPreferences.Editor;
import android.graphics.Bitmap.Config;
import android.graphics.Shader;
import android.os.Bundle;
import android.text.Editable;
import android.widget.CheckBox;
import android.widget.CompoundButton;
import android.widget.CompoundButton.OnCheckedChangeListener;

public class TaskSettingActivity extends Activity {
private CheckBox cb_show_system;
private SharedPreferences sp;
protected void onCreat(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_task_setting);
sp = getSharedPreferences("Config", MODE_PRIVATE);
cb_show_system = (CheckBox) findViewById(R.id.cb_show_system);
cb_show_system.setChecked(sp.getBoolean("showsystem", false));
cb_show_system.setOnCheckedChangeListener(new OnCheckedChangeListener() {

@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isCheked) {
Editor editor = sp.edit();
editor.putBoolean("showsystem", isCheked);
editor.commit();

}
});
}

}
为什么跳转之后就成了空白页呢

Answer 1

protected void onCreat(Bundle savedInstanceState) {

这句写错了，导致没有创建，改成下面的
protected void onCreate(Bundle savedInstanceState) {
