如何以编程方式隐藏按钮？

Question

我有一个RelativeLayout包含两个按钮.它们相互重叠.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="#FFFFFF">


<Button android:text="Play"  
    android:id="@+id/play"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:layout_alignParentBottom = "true">
</Button>

<Button android:text="Stop "
    android:id="@+id/stop" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content"
    android:layout_alignParentBottom = "true">
</Button>


</RelativeLayout>

我想以编程方式一次只显示一个按钮,同时调用其click事件.

我尝试过:

playButton.setVisibility(1);

但它不起作用.以下是我想要做的一个例子.

playButton = (Button) findViewById(R.id.play);
playButton.setVisibility(1);
playButton.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        //when play is clicked show stop button and hide play button

    }
});

Answer 1

您可以使用以下代码:

playButton = (Button) findViewById(R.id.play);
playButton.setVisibility(View.VISIBLE);
playButton.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        //when play is clicked show stop button and hide play button
        playButton.setVisibility(View.GONE);
        stopButton.setVisibility(View.VISIBLE);
    }
});

试试下面的代码 -

playButton.setVisibility(View.INVISIBLE);

要么 -

playButton.setVisibility(View.GONE);

再次展示 -

playButton.setVisibility(View.VISIBLE);
