Android 如何将值从TabActivity发送到Activity？

在我的TabActivity中，我向其他活动发送值，如何做到这一点

在本活动中，我如何将捆绑包发送到其他活动请告诉我 如何将值传递给我的其他ReceivedList活动请告诉我

    public class TabViewForSendAndRecv extends TabActivity{

private TabActivity tabhost1;

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.tabviewforsendandrecv);


    Bundle bundle = getIntent().getExtras();
    String stuff = bundle.getString("number"); 



         final TabHost tabHost = getTabHost(); 



      TextView txtTab = new TextView(this);
        txtTab.setText("Received Alerts");
        txtTab.setPadding(8, 9, 8, 9);
        txtTab.setTextColor(Color.WHITE);
        txtTab.setTextSize(14);
        //txtTab.setTypeface(localTypeface1);
        txtTab.setGravity(Gravity.CENTER_HORIZONTAL |                                            Gravity.CENTER_VERTICAL);


        TabHost.TabSpec spec;

        // Initialize a TabSpec for each tab and add it to the TabHost
        spec = tabHost.newTabSpec("Tab1").setIndicator(txtTab).
        setContent(new Intent(this, ReceivedList.class).addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP));


        tabHost.addTab(spec);




      //tab 2


        TextView txtTab1 = new TextView(this);
        txtTab1.setText("Sent Alerts");
        txtTab1.setPadding(8, 9, 8, 9);
        txtTab1.setTextColor(Color.WHITE);
        txtTab1.setTextSize(14);
        //txtTab.setTypeface(localTypeface1);
        txtTab1.setGravity(Gravity.CENTER_HORIZONTAL | Gravity.CENTER_VERTICAL);


        TabHost.TabSpec spec1;
        // Initialize a TabSpec for each tab and add it to the TabHost
        spec1 = tabHost.newTabSpec("Tab2").setIndicator(txtTab1).setContent(new Intent(this, SentList.class).addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP));



        tabHost.addTab(spec1);

您可以按如下方式传递此数据：

编辑此行：

setContent（新的意图（这个，ReceivedList.class）。addFlags（意图.FLAG\u活动\u清除\u顶部））

至：

Intent receivedListIntent = new Intent(this,ReceivedList.class).addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

receivedListIntent.putExtra("number", stuff);

setContent(receivedListIntent);

您可以在ReceivedList活动中获取此数据：

Bundle bundle = getIntent().getExtras();
String stuff = bundle.getString("number");

仍然有一种方法可以在多个活动之间交换数据。为此，您需要创建一个类应用程序类。并为数据创建公共字段。您可以在所有活动中设置或获取此字段
