這就是你需要使用共享首選項的方式。

我將要展示的senerio是檢查這個 Activity 是否在第一次運行時運行。

以下是你在創建方法中所做的操作://SharePrefernces

SharedPreferences appIntro = null;

@Override

protected void onCreate(Bundle savedInstanceState) {

//Check if the Application is Running for the First time

appIntro = getSharedPreferences("hasRunBefore_appIntro", 0);//load the preferences

Boolean hasRun = appIntro.getBoolean("hasRun_appIntro", false);//see if it's run before, default no

//If FirstTime

if (!hasRun) {

//code for if this is the first time the application is Running

//Display Activity

super.onCreate(savedInstanceState);

setContentView(R.layout.app_intro_activity);

//Button to send Confirmation back

Button btn_ok = (Button) findViewById(R.id.appintro_btn_ok);

btn_ok.setOnClickListener(new View.OnClickListener() {

public void onClick(View arg0) {

//Save information that this application has run for the first time

SharedPreferences settings = getSharedPreferences("hasRunBefore_appIntro", 0);

SharedPreferences.Editor edit = settings.edit();

edit.putBoolean("hasRun_appIntro", true);

edit.commit();//apply

Intent intent = new Intent(Application_Intro_Activity.this, MainActivity.class);

startActivity(intent);

//close Activity

finish();

}

});

}//End of if(firstTime)

else {

//code if the Application has run before

super.onCreate(savedInstanceState);

//Navigate Directly to MainActivity

Intent intent = new Intent(Application_Intro_Activity.this, MainActivity.class);

startActivity(intent);

//close Activity

finish();

}

}//End of OnCreate()
