Question

嗨其他编码员我真的需要帮助，我真的没有想法，尝试了很多想法，没有人为我工作....

我正忙于排放调查应用程序，我正在尝试更改if语句中的标签，如果广播的值为1，则转到第二个标签，然后自动到第三个...附件是片段，请帮忙，我真的很感激....！

第一张图片是我将数据发送回第一个标签（目前所有人仍在工作）

    loadB.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            TabActivity tabs = (TabActivity) getParent();
            tabs.getTabHost().setCurrentTab(0);
            sendData3();
        }
        private void sendData3() {
            take = "1";
            Intent dataIntent = new Intent();
            dataIntent.setAction("com.example.e3soft.receiver");
            dataIntent.putExtra("taken", take);
            sendBroadcast(dataIntent);
            Toast.makeText(getBaseContext(), "Working", Toast.LENGTH_LONG).show();
        }
    });

如果没有if语句一切正常，请帮助........！

private void receiveData() {
    // TODO Auto-generated method stub
    BroadcastReceiver receiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            // TODO Auto-generated method stub
            take = intent.getStringExtra("taken");

        }

    };

    IntentFilter filter = new IntentFilter();
    filter.addAction("com.example.e3soft.receiver");
    registerReceiver(receiver, filter);
    changeTab();
}

protected void changeTab() {
    // TODO Auto-generated method stub
    Toast.makeText(getApplicationContext(), take, Toast.LENGTH_LONG).show();
    try {
        if (take.equals("1")) {
            populateVariables();
            TabActivity tabs = (TabActivity) getParent();
            tabs.getTabHost().setCurrentTab(1);
            sendData();
        }
    } catch (Exception ex) {
        Toast.makeText(getApplicationContext(), "Error", Toast.LENGTH_LONG)
                .show();
    }
}

将此代码移到onReceive中：

IntentFilter filter = new IntentFilter();
filter.addAction("com.example.e3soft.receiver");
registerReceiver(receiver, filter);
changeTab();

如何从广播变量中更改if语句中的选项卡？
