Android-在onClick操作中隐藏按钮

问题描述

限时删除！！

在这样的onClick动作中，我需要隐藏一个按钮:

I need to hide a button during an onClick action like this:

    public void onClick(View view) {
    switch (view.getId()){
        case R.id.button1:

            Button button2 = (Button) findViewById(R.id.button2);
            button2.setVisibility(View.GONE);

            //Some methods
            //...

            button2.setVisibility(View.VISIBLE);

            break;
    }

但是可见性仅在onClick之后改变，我该怎么做才能在onstrong中隐藏按钮 ?

But the visibility changes only after the onClick, what could I do to hide the button during the onClick?

谢谢

推荐答案

当然，因为您正在同一线程中执行所有操作，因此可能会发现可见性发生变化，请尝试以下操作:

of course because you are executing all operation in the same thread you may notice the visibility changement, try this :

public void onClick(View view) {
switch (view.getId()){
    case R.id.button1:

        final button2 = (Button) findViewById(R.id.button2);
        button2.setVisibility(View.GONE);

        setVisibility(GONE);
        new Thread(new Runnable() {
            @Override
            public void run() {
                //your work

                runOnUiThread(new Runnable() { //resetting the visibility of the button
                    @Override
                    public void run() {
                        //manipulating UI components from outside of the UI Thread require a call to runOnUiThread
                        button2.setVisibility(VISIBLE);
                    }
                });
            }
        }).start();

        break;
}
}
