请看下面的例子我认为这是OnUI问题所以我在下面的代码。我希望这对任何人都有帮助让我知道你的结果谢谢你的时间。

public class MyTransferListener implements FTPDataTransferListener {
    public void started() {
        runOnUiThread(new Runnable() {
            public void run() {
                //btn.setVisibility(View.GONE);
                // Transfer started
                Toast.makeText(getBaseContext(), " Upload Started ...", Toast.LENGTH_SHORT).show();
            }
        });

        // System.out.println(" Upload Started ...");
    }
    public void transferred(final int length) {
        // Yet other length bytes has been transferred since the last time
        // this
        // method was called
        runOnUiThread(new Runnable() {
            public void run() {
                Toast.makeText(getBaseContext(), " transferred ..." + length, Toast.LENGTH_SHORT).show();
            }
        });

        // System.out.println(" transferred ..." + length);
    }
    public void completed() {
        runOnUiThread(new Runnable() {
            public void run() {
                //btn.setVisibility(View.VISIBLE);
                // Transfer completed

                Toast.makeText(getBaseContext(), " completed ...", Toast.LENGTH_SHORT).show();
            }
        });

        // System.out.println(" completed ..." );
    }

    public void aborted() {
        runOnUiThread(new Runnable() {
            public void run() {
                //btn.setVisibility(View.VISIBLE);
                // Transfer aborted
                Toast.makeText(getBaseContext(), " transfer aborted , please try again...",
                        Toast.LENGTH_SHORT).show();
            }
        });

        // System.out.println(" aborted ..." );
    }
    public void failed() {
        runOnUiThread(new Runnable() {
            public void run() {
                //btn.setVisibility(View.VISIBLE);
                // Transfer failed
                System.out.println(" failed ...");
            }
        });
    }
}
