如何在 Android 中删除按钮或使其不可见?

How can I remove a button in Android, or make it invisible?

推荐答案

将按钮可见性设置为 GONE(按钮将被完全移除"——按钮空间可用于其他小部件)或 INVISIBLE(按钮将变为透明"——它的空间将不能用于其他小部件):

Set button visibility to GONE (button will be completely "removed" -- the buttons space will be available for another widgets) or INVISIBLE (button will became "transparent" -- its space will not be available for another widgets):

View b = findViewById(R.id.button);
b.setVisibility(View.GONE);

或在 xml:

<Button ... android:visibility="gone"/>
