Question

我想在主办提出看法的活动时展示菜单。这里是我的表态活动守则。

public class Tabs3 extends TabActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        final TabHost tabHost = getTabHost();

        tabHost.addTab(tabHost.newTabSpec("tab1").setIndicator("list")
                .setContent(new Intent(this, List1.class)));

        tabHost.addTab(tabHost.newTabSpec("tab2").setIndicator("photo list")
                .setContent(new Intent(this, List8.class)));
    }

    @Override
    public boolean onPrepareOptionsMenu(Menu menu) {
        menu.removeGroup(0);

        menu.add(0, 0, 0, "Home").setIcon(
                android.R.drawable.ic_menu_preferences);

        return super.onPrepareOptionsMenu(menu);
    }

    @Override
    public boolean onMenuItemSelected(int featureId, MenuItem item) {
        switch (item.getItemId()) {
        case 0:
            setResult(10);
            finish();
            return true;
        }

        return super.onMenuItemSelected(featureId, item);
    }
}

现在,当一是迫在眉睫的和roid的菜单,onPrepareOptions Menu被称作是正确的,但在选择菜单时,没有发生。我还在上打了我的代码和控制。

请提供帮助。

I got my solution.. i dont whether it is perfect way to do it but it is working..

我们不使用<条码>选择,而是使用<条码>。

Here is the final code:

public class Tabs3 extends TabActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        final TabHost tabHost = getTabHost();

        tabHost.addTab(tabHost.newTabSpec("tab1").setIndicator("list")
                .setContent(new Intent(this, List1.class)));

        tabHost.addTab(tabHost.newTabSpec("tab2").setIndicator("photo list")
                .setContent(new Intent(this, List8.class)));
    }

    @Override
    public boolean onPrepareOptionsMenu(Menu menu) {
        menu.removeGroup(0);

        menu.add(0, 0, 0, "Home").setIcon(
                android.R.drawable.ic_menu_preferences);

        return super.onPrepareOptionsMenu(menu);
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
        case 0:
            setResult(10);
            finish();
            return true;
        }

        return super.onOptionsItemSelected(item);
    }
}
