android - 在每个选项卡中调用相同的 Activity setContent()

Question

我有一个选项卡 Activity ，它的每个选项卡都调用相同的 Activity 让我们说 MyTabInterface。所以我希望我的 MyTabInterface 可以获取按下哪个选项卡的信息。我已尝试使用下面的代码执行此操作，但似乎没有用

intent = new Intent().setClass(this,MyTabInterface.class);
intent.putExtra("interface",tabs.elementAt(0).getAction());
intent.putExtra("data",tabs.elementAt(0).getData());
spec = tabHost.newTabSpec(tabs.elementAt(0).getName()).setIndicator(tabs.elementAt(0).getLabel().toString(),res.getDrawable(R.drawable.ic_tab_artists)).setContent(intent);
tabHost.addTab(spec);


intent = new Intent().setClass(this,MyTabInterface.class);
intent.putExtra("interface","table");
intent.putExtra("data","table_data");
spec= tabHost.newTabSpec(tabs.elementAt(1).getName()).setIndicator(tabs.elementAt(1).getLabel().toString(),res.getDrawable(R.drawable.ic_tab_artists))
.setContent(intent);
tabHost.addTab(spec);

我的 View 会根据 putExtra 的详细信息而改变。这里在两个选项卡中调用相同的 Activity 类。拳头选项卡正确显示。但第二个显示与第一个相同。

我该如何解决这个问题？

这是 TabActivity 的代码 fragment ，希望对您有所帮助:

public class InfralineTabWidget extends android.app.TabActivity{

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

    @SuppressWarnings("unused")
    Resources res = getResources();
    TabHost tabHost = (TabHost)getTabHost();

    TabHost.TabSpec spec;
    @SuppressWarnings("unused")
    Intent intent;
 tabHost.getTabWidget().setBackgroundDrawable(getResources().getDrawable(R.drawable.bluenavbar));
    TextView  txtTab = new TextView(this);
        txtTab.setText(getString(R.string.top_news));
        txtTab.setPadding(8, 9, 8, 9);
        txtTab.setTextColor(Color.WHITE);
        txtTab.setTextSize(14);
    txtTab.setGravity(Gravity.CENTER_HORIZONTAL | Gravity.CENTER_VERTICAL);
        txtTab.setBackgroundResource(R.drawable.tab_news);
    intent = new Intent().setClass(this, TopNewsGroup.class);
    spec = tabHost.newTabSpec("topNews").setIndicator(txtTab).setContent(new Intent(this,TopNewsGroup.class).addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP ));
    tabHost.addTab(spec);

    TextView  txtTab1 = new TextView(this);
    txtTab1.setText(getString(R.string.power));
    txtTab1.setPadding(8, 9, 8, 9);
    txtTab1.setTextColor(Color.WHITE);
    txtTab1.setTextSize(14);
    txtTab1.setTypeface(localTypeface1);
    txtTab1.setGravity(Gravity.CENTER_HORIZONTAL | Gravity.CENTER_VERTICAL);
    txtTab1.setBackgroundResource(R.drawable.tab_power);
    intent = new Intent().setClass(this, PowerGroup.class);
    spec = tabHost.newTabSpec("power").setIndicator(txtTab1).setContent(new Intent(this,PowerGroup.class).addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP ));
    tabHost.addTab(spec);


    tabHost.setCurrentTab(0);
        tabHost.getTabWidget().getChildAt(0).getLayoutParams().height = 100;
        tabHost.getTabWidget().getChildAt(1).getLayoutParams().height = 100;

        tabHost.getTabWidget().getChildAt(0).getLayoutParams().width = 160;
        tabHost.getTabWidget().getChildAt(1).getLayoutParams().width = 160;    

}
