Question

我有一个屏幕，我存储一个电话号码然后转到另一个屏幕并启动活动的主要部分，我发送文本按摩，我试图获取我在第一个活动中输入的数字。我有所有代码发送消息，但它不会从前一个活动获得数字。这是第一个活动的代码：

public class StoreNumberActivity extends Host_Setting_PageActivity {
     /** Called when the activity is first created. */
    @Override


     public void onCreate(Bundle savedInstanceState) {
            super.on``Create(savedInstanceState);
            setContentView(R.layout.notificationsettings);

            final EditText editText= (EditText) findViewById(R.id.HostPhoneNumber);

             //Juston class to schedule edit
            Button Save = (Button) findViewById(R.id.SaveBtn);
            Save.setOnClickListener(new View.OnClickListener() {
                public void onClick(View view) {
                    Toast.makeText(StoreNumberActivity.this, "Number was Saved Successfully", Toast.LENGTH_LONG).show();

                }
            });
             Button Send = (Button) findViewById(R.id.SendBtn);
              Send.setOnClickListener(new View.OnClickListener() {
                  public void onClick(View view) {
                      String Number  =  editText.getText().toString();
                      Intent myIntent = new Intent(StoreNumberActivity.this, Host_Setting_PageActivity.class);
                      myIntent.putExtra("Phone Num", Number);
                      startActivity(myIntent);
                  }


and my code from the second activity:



 public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);


    /** setting the view of the activity to xml */
    setContentView(R.layout.messageme);
    final Bundle bundle = getIntent().getExtras();

    final EditText editText= (EditText) findViewById(R.id.yourname);
    final EditText phonenumber= (EditText) findViewById(R.id.phone);
    final EditText emailaddress= (EditText) findViewById(R.id.email);
    final EditText messagebox= (EditText) findViewById(R.id.messages);
    final EditText number = (EditText) findViewById(R.id.HostPhoneNumber);

    button= (Button) findViewById(R.id.btn);
    button.setOnClickListener(new View.OnClickListener() {

    public void onClick(View v) {
    // TODO Auto-generated method stub
        Intent myIntent = getIntent(); // this is just for example purpose
        myIntent.getStringExtra("PhoneNum");
        String Number = bundle.getString("Phone Num");
        String Name  =  editText.getText().toString();
        String Phone  = phonenumber.getText().toString();
        String Email  = emailaddress.getText().toString();
        String Message  = messagebox.getText().toString();



        sendSMS(Number, "Name: " + Name + "\n" + "\n" + "Email: " + Email + "\n" + "\n" + "Phone: " + Phone + "\n" + "\n" + Message);
    }
