只有选择飞溅preference checkedboxs一个复选框 [英] Only select one checkbox of splash preference checkedboxs

查看:266
本文介绍了只有选择飞溅preference checkedboxs一个复选框的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我的应用程序开始依赖于用户的preferance有三种不同checkedbox:

无飞溅和音乐1-启动应用程序。

飞溅2 - 启动应用程序而已。

3启动应用程序与spalsh和音乐。

用C的工作低于$ C $完美。

但仍然是两个点来实现:

第一个只有一个复选框应进行检查。

第二个你检查checkboxs中的任何一个,你以后preFER然后回到mainactivity,在这里你可以退出该应用程序或者通过使用后退按钮或< STRONG>退出按钮我已经在我的选项菜单中,问题是,无论是使用返回按钮退出按钮它不响应第一点击,我需要点击两次退出应用程序。

但我不能达到它,

任何帮助,请将AP preciated。

更新3(整个项目):

-1-酮选中复选框完美实现。

2 - 或者使用后退按钮或退出按钮MainActivity,不先点击反应,我必须单击两次或三次退出应用程序。

解决方案

第一只有一个复选框应进行检查。

不知道如何使这个短暂而简单的答案,但挂在身边,这个工程。

创建你从你的活动调用preference活动。

使用这样的事情在你的onOptionSelected:

 情况下R.id. preFS:
        意图P =新的意图(MainActivity.this,prefs.class);
        startActivity(对);
        打破;
 

这是prefs.class

复选框preference飞溅;

复选框preference no_splash_music;


@覆盖
保护无效的onCreate(包savedInstanceState){

    super.onCreate(savedInstanceState);

    加preferencesFromResource(R.xml preFS);



    飞溅=(复选框preference)找到preference(扑通);
    splash_music =(复选框preference)找到preference(splash_music);
    no_splash_music =(复选框preference)找到preference(without_splash_screen);

    splash.setOn preferenceChangeListener(新在preferenceChangeListener(){

        @覆盖
        公共布尔在preferenceChange(preference preference,
                对象为newValue){
            // TODO自动生成方法存根

            splash.setChecked(真正的);
            splash_music.setChecked(假);
            no_splash_music.setChecked(假);

            返回true;
        }

    });

    splash_music
            .setOn preferenceChangeListener(新在preferenceChangeListener(){

                @覆盖
                公共布尔在preferenceChange(preference preference,
                        对象为newValue){
                    // TODO自动生成方法存根

                    splash.setChecked(假);
                    splash_music.setChecked(真正的);
                    no_splash_music.setChecked(假);

                    返回true;
                }

            });

    no_splash_music
            .setOn preferenceChangeListener(新在preferenceChangeListener(){

                @覆盖
                公共布尔在preferenceChange(preference preference,
                        对象为newValue){
                    // TODO自动生成方法存根

                    splash.setChecked(假);
                    splash_music.setChecked(假);
                    no_splash_music.setChecked(真正的);

                    返回true;
                }

            });

   }

 }
 

不要忘了将它添加到清单:

    &LT; /活性GT;
 

在prefs.xml文件是一样的,你贴的人。

让我知道如果你得到任何错误。我测试过它,它工作在这里很好。

第二

不知道为什么你必须点击两次。但它可能被飞溅没有完成,只需调用一个新的意图引起的。 试试这个在任何你开始你的mainclass从飞溅:

 终于{
            意向意图=新的意图(Splash.this,MainActivity.class);
            startActivity(意向);
            完();

            }
 

现在,我看过了你的项目,并发现了它为什么有那么越野车。

主要的原因:

 如果(音乐==真)
    ourSong.start();

    螺纹定时器=新的Thread(){
 

下面你缺少一个括号内为if语句,导致线程每次运行。因此,必须在同一时间运行两个MainActivities。

其他注意事项:使用如果的所有值。我建议你​​使用否则,如果。

和我做了一个小的清理工作。

在这里你走。享受:

链接到Splash.java

您可以解决最后的问题是多方面的。其中之一是这样的:

  //如果否则,如果添加此下方对方在splass.java声明
否则,如果(without_splash_screen ==假放;&安培;飞溅==假放;&功放;音乐== FALSE){
//把任何你想要的发生,如果他们没有进行检查。这仅仅是一个例子。

I have app starting depend on user preferance with three different checkedbox :

1- start app without splash and music .

2- start app with splash only .

3- start app with spalsh and music .

with the below code its work perfectly .

But still two point to be achieved :

FIRST only one checkbox should be checked .

SECOND after you checked any one of checkboxs as you prefer then go back to mainactivity , here you can exit the app either by use back button or exit button which i already have it in my option menu , the problem is that either using back button or exit button it doesn't respond to first click , i have to click twice to exit the app.

but i cant achieve it ,

any help please will be appreciated .

i tried also the below code but it doesn't change any thing , still all chechboxs can be checked :

Any advice , thanks.

UPDATE 3 (WHOLE PROJECT):

1- one checkbox checked achieved perfectly .

2- either using back button or exit button in MainActivity , doesn't respond to first click , i have to click twice or three times to exit the app.

解决方案

"FIRST only one checkbox should be checked ."

Not sure how to make this a short and easy answer, but hang with me, this works.

Create a preference activity that you call from your activity.

Use something like this in your onOptionSelected:

  case R.id.prefs:
        Intent p = new Intent(MainActivity.this, Prefs.class);
        startActivity(p);
        break;

This is the Prefs.class

public class Prefs extends PreferenceActivity {
CheckBoxPreference splash;
CheckBoxPreference splash_music;
CheckBoxPreference no_splash_music;


@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);

    addPreferencesFromResource(R.xml.prefs);



    splash = (CheckBoxPreference) findPreference("splash");
    splash_music = (CheckBoxPreference) findPreference("splash_music");
    no_splash_music = (CheckBoxPreference) findPreference("without_splash_screen");

    splash.setOnPreferenceChangeListener(new OnPreferenceChangeListener() {

        @Override
        public boolean onPreferenceChange(Preference preference,
                Object newValue) {
            // TODO Auto-generated method stub

            splash.setChecked(true);
            splash_music.setChecked(false);
            no_splash_music.setChecked(false);

            return true;
        }

    });

    splash_music
            .setOnPreferenceChangeListener(new OnPreferenceChangeListener() {

                @Override
                public boolean onPreferenceChange(Preference preference,
                        Object newValue) {
                    // TODO Auto-generated method stub

                    splash.setChecked(false);
                    splash_music.setChecked(true);
                    no_splash_music.setChecked(false);

                    return true;
                }

            });

    no_splash_music
            .setOnPreferenceChangeListener(new OnPreferenceChangeListener() {

                @Override
                public boolean onPreferenceChange(Preference preference,
                        Object newValue) {
                    // TODO Auto-generated method stub

                    splash.setChecked(false);
                    splash_music.setChecked(false);
                    no_splash_music.setChecked(true);

                    return true;
                }

            });

   }

 }

And don't forget to add it to the Manifest:

  <activity
        android:name="com.lordmarty.testforlools.Prefs"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="com.lordmarty.testforlools.PREFS" />

            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>

The prefs.xml file is the same as the one you posted.

Let me know if you get any errors. I've tested it, and it works fine here.

"SECOND"

Not sure why you have to click twice. But it might be caused by the splash not finishing, just calling a new intent. Try this where ever you start your mainclass from the splash:

  finally{
            Intent intent = new Intent(Splash.this,    MainActivity.class);                                     
            startActivity(intent);
            finish();

            }

Now, I've looked over your project and found out why it where so buggy.

Main reason:

     if (music == true)     
    ourSong.start();

    Thread timer = new Thread(){

Here you are missing a brackets for the if statement, causing the thread to run everytime. Therefore you have two MainActivities running at the same time.

Other notes: You use "if"'s for all the values. I suggest you use "else if".

And I did a small cleanup.

Here u go. Enjoy:

Link to Splash.java

You can solve the last problem in many ways. One of them being this:

// add this below the other if else if statements in the splass.java
else if(without_splash_screen == false && splash == false && music == false){
//put whatever you want to happen if none of them are checked. This is just an example.
setContentView(R.layout.splash); 
        setContentView(R.layout.splash); 
        Thread timer = new Thread() { 
            public void run() { 
                try { 
                    sleep(2000); 
                } catch (InterruptedException e) { 
                    e.printStackTrace(); 
                } finally { 
                    Intent intent = new Intent(Splash.this, 
                            MainActivity.class); 
                    startActivity(intent); 
                    finish(); 


                } 
            } 
        }; 
        timer.start();
