android - 只有创建 View 层次结构的原始线程才能触及它的 View 。 Paypal MPL Android

Question

我正在使用 Paypal 的 MPL 开发处理捐赠的应用程序当你调用下一段代码时

// Use checkout to create our Intent.
Intent checkoutIntent = PayPal.getInstance().checkout(payment, this,
        new ResultDelegate());

// Use the android's startActivityForResult() and pass in our
// Intent.
// This will start the library.
startActivityForResult(checkoutIntent, REQUEST_PAYPAL_CHECKOUT);
Log.i(TAG, "Executo todo el procedimiento de paypal.");

付款完成后
1.- 使用 Paypal 凭据登录
2.- 在下一个 Activity 中按支付
3.- 输入电话号码和密码
4.- 按创建 Pin 按钮

显示下一个错误

Answer 1

您需要在

中设置 TextView 的文本

runOnUiThread(new Runnable() {
    @Override
    public void run() {
         //set TextView text here.  Because only the UI thread can update UI.
    }
});
