问:

我有一个屏幕,我在其中存储了一个电话号码,然后转到另一个屏幕并启动活动的主要部分,我在其中发送文本按摩,我试图获取我在第一个活动中输入的号码。我有发送消息的所有代码,但它不会从上一个活动中获取数字。这是我的第一个活动的代码:

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);
                  }
    

以及我来自第二个活动的代码:

 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);
    }

这回答了你的问题吗?如何在 Android 应用程序中的 Activity 之间传递数据?
