Android新接口——一步实现IP拨号器

MainActivity

package com.example.zong.ipbohaoqi;

import android.content.SharedPreferences;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.EditText;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {
    private EditText et_ipnumber;
    private SharedPreferences sp;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        et_ipnumber = (EditText) findViewById(R.id.et_ipnumber);
        sp = getSharedPreferences("config", MODE_PRIVATE);
        et_ipnumber.setText(sp.getString("ipnumber", ""));
    }

    public void click(View view) {
        String ipnumber = et_ipnumber.getText().toString().trim();
        SharedPreferences.Editor editor = sp.edit();
        editor.putString("ipnumber", ipnumber);
        editor.commit();
        Toast.makeText(this, "设置成功", 0).show();
    }
}

OutCallReceiver

package com.example.zong.ipbohaoqi;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.SharedPreferences;


public class OutCallReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        String outcallnumber = getResultData();
        SharedPreferences sp = context.getSharedPreferences("config", Context.MODE_APPEND);
        String ipnumber = sp.getString("ipnumber", "");
        setResultData(ipnumber + outcallnumber);
    }
}
