如何从活动类数据的PhoneStateListener类？ [英] how to get data from activity class to the PhoneStateListener class?

问题描述

我有一个问题在我不能获得活动类数据的PhoneStateListener类。

I have a problem in which i cant get data from activity class to the PhoneStateListener class.

为了更好地了解code是波纹管： -

for better understanding the code is as bellow:-

//这是从那里我要发送的数据或类字符串

//this is the class from where i want to send the data or string

package net.cellobject.blockingincomingcall;

import android.app.Activity;

import android.content.SharedPreferences;

import android.os.Bundle;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import android.widget.EditText;

import android.widget.Toast;



public class SecondTab extends Activity

{

    EditText e1;

    Button b1;

    protected void onCreate(Bundle savedInstanceState) 

    {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.setting);

        e1=(EditText)findViewById(R.id.edt1);

        b1=(Button)findViewById(R.id.b1);



        LoadPreferences();



        b1.setOnClickListener(new OnClickListener()

        {

            public void onClick(View v) 

            {

                String msg=e1.getText().toString();

                SavePreferences("msg1",msg);

                LoadPreferences();



                if(msg=="")

                {



                Toast.makeText(getApplicationContext(), "First 


                                               Enter the message then save it"

                                               ,Toast.LENGTH_LONG).show();

                    e1.requestFocus();

                }

            }

        });



    }


    private void LoadPreferences() 

    {

        SharedPreferences shp= getPreferences(MODE_PRIVATE);

        String s1=shp.getString("msg1","");

        e1.setText(s1);



    }

    private void SavePreferences(String key, String msg) 

    {

        SharedPreferences shp= getPreferences(MODE_PRIVATE);

        SharedPreferences.Editor editor=shp.edit();

        editor.putString(key, msg);

        editor.commit();



    }

}

//这是我想要得到的数据或字符串，它是PhoneStateListener扩展的类？

//this is the class where i want to get the data or string which is extends with PhoneStateListener?

                break;

        }

        super.onCallStateChanged(state, incomingNumber);

    {

        sms.sendTextMessage(incomming, null, string, null, null);



    }

}

即时发布一个非常简单的方法来存储和获得preferences，使用此我将解决您的相关存储和检索preferences问题。

im posting a very simple method to store and get preferences, use this i will solve your problem related to store and retrieve preferences.

public class Preferences {


public static void record(String key,Context context,String value)
{
    SharedPreferences pref=PreferenceManager.getDefaultSharedPreferences(context);
    SharedPreferences .Editor editor=pref.edit();

    editor.putString(key,value );
    editor.commit();


}
public static String getRecord(String key,Context context)
{
    return PreferenceManager.getDefaultSharedPreferences(context).getString(key,PREF_DEFAULT_VALUE);

}

}
