Vì vậy, tôi đang cố gắng tạo hoạt ảnh khi tôi đặt khả năng hiển thị của một tuyến tính với các tiện ích khác, từ GONE sang VISIBLE và ngược lại. Tôi đang sử dụng các nút chuyển đổi để hiển thị và ẩn. Đây là một hình ảnh để hiển thị những gì tôi muốn làm:
Tôi có thể hiển thị và ẩn, nhưng tôi không làm theo cách tôi có thể tạo hoạt ảnh trượt chính xác .... :(
Đây là xml của tôi:

Và đây là mã java gọi sự kiện nút:
final ToggleButton bt=(ToggleButton) findViewById(R.id.mostrar);
bt.setOnClickListener(new OnClickListener() {

slide.setDuration(500);
slide.setFillAfter(true);

findViewById(R.id.informgeral).setVisibility(View.VISIBLE);;
} else {
/* TranslateAnimation slide = new TranslateAnimation(0, 0, 0,

slide.setFillAfter(true);

}
}
});
