如何从标签活动通过意向

Question

我想从这个活动

public class HomeActivity extends android.app.TabActivity 
{ 
    String uid; 
protected void onCreate(Bundle savedInstanceState) 
     { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_home); 
    TabHost tabHost = getTabHost(); 
    Intent intent = getIntent(); 
    uid = intent.getStringExtra("uid"); 
    // Tab for ActivityOne 
    TabSpec photospec = tabHost.newTabSpec("Home"); 
    photospec.setIndicator("Home", getResources().getDrawable(R.drawable.one)); 
    Intent photosIntent = new Intent(this, TabhomeActivity.class); 
    photosIntent.putExtra("uid", uid); 
    // startActivityForResult(photosIntent,0); 
    photospec.setContent(photosIntent); 

    // Tab for ActivitySecond 
    TabSpec songspec = tabHost.newTabSpec("Today's Meeting"); 
    // setting Title and Icon for the Tab 
    songspec.setIndicator("Today's Meeting", 
              getResources().getDrawable(R.drawable.one)); 
    Intent songsIntent = new Intent(this,TodaysmeetingActivity.class); 
    songspec.setContent(songsIntent); 
    // Adding all TabSpec to TabHost 
    tabHost.addTab(photospec); // Adding photos tab 
    tabHost.addTab(songspec); // Adding songs tab 
    } 
} 

这一活动送超值值发送到活动..

public class TabhomeActivity extends Activity { 

Button button1; 
Button button2; 
Button button3; 
TextView txtview,shwname; 
String uid; 

@Override 
public void onCreate(Bundle savedInstanceState) 
{ 

    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_tabhome); 
    Intent intent = getParent().getIntent(); 
    uid = intent.getStringExtra("uid"); 
    shwname=(TextView)findViewById(R.id.textView3); 
    shwname.setText("Hi\t"+uid); 
} 

谁能帮助我？请。提前致谢。

Answer 1

发送时：

Intent i = new Intent(); 
intent.putString("uid", uid); 

在接收时：

Intent intent = getIntent(); 
Bundle extras = intent.getExtras(); 
uid = getIntent().getExtras().getString("uid"); 

或（使用束）：

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    savedInstanceState = getIntent().getExtras(); 
    uid = savedInstanceState.getString("uid"); 
} 

Answer 2

尝试以下。

Intent intent = getIntent(); 
Bundle extras = intent.getExtras(); 
uid = getIntent().getExtras().getString(YOUR_KEY); 

同样的数据设置到意图使用时

extras.putString(YOUR_KEY, YOUR_VALUE);
