我有一个 tabActivity,我将活动设置为选项卡的内容。从一项活动中,我尝试禁用 tabhost。如何实现这一目标。

  public class Main extends TabActivity {

public static final File sdcard = Environment.getExternalStorageDirectory();

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

    TabHost tabHost = getTabHost();

    TabSpec homespec = tabHost.newTabSpec("Home");
    homespec.setIndicator("Home");
    Intent homeIntent = new Intent(this, HomeActivity.class);
    homespec.setContent(homeIntent);

    TabSpec presentspec = tabHost.newTabSpec("Presentations");
    presentspec.setIndicator("Presentations");
    Intent presentIntent = new Intent(this, PresentationActivity.class);
    presentspec.setContent(presentIntent);

    TabSpec pendspec = tabHost.newTabSpec("Pending Submission");
    pendspec.setIndicator("Pending Submission" /*getResources().getDrawable(R.drawable.icon_videos_tab)*/);
    Intent pendingIntent = new Intent(this, PendingActivity.class);
    pendspec.setContent(pendingIntent);

    TabSpec syncspec = tabHost.newTabSpec("Synchronization");
    syncspec.setIndicator("Synchronization" /*getResources().getDrawable(R.drawable.icon_videos_tab)*/);
    Intent syncIntent = new Intent(this, SyncActivity.class);
    syncspec.setContent(syncIntent);

    tabHost.addTab(homespec); 
    tabHost.addTab(presentspec); 
    tabHost.addTab(pendspec);
    tabHost.addTab(syncspec);


}
}

这是我的 tbb 活动

  public class SyncActivity extends Activity {
     class DownloadWebPageTask extends AsyncTask<String, Void, String> {

                   @Override
        protected void onPostExecute(String result) {
            end();
        }

        @Override
        protected String doInBackground(String... params) {

              progress.setVisibility(ProgressBar.VISIBLE);
              progress.setProgress(0);
              progress.setMax(1000);

            int currentPosition= 0;

            while (currentPosition<1000) {
                try {
                    Thread.sleep(500);
                    currentPosition+=100;
                } catch (InterruptedException e) {
                    return null;
                } catch (Exception e) {
                    return null;
                }            
                progress.setProgress(currentPosition);

            }
            return null;
        }
      }
    }

当我尝试这个时,其他标签应该被禁用

TabActivity 现在已弃用,请尝试选项卡和片段,您可以在此处找到更多信息

您可以使用布尔标志来处理启用的选项卡,当您尝试更改选项卡时,首先您可以检查选项卡是否处于活动状态。
