我试图设置我的 imageview 、 button 和 textview 的可见性。但是当我运行程序时它们仍然存在。我尝试了 View.GONE，但这只是删除了所有的 textview、imageview 和按钮。但我只想隐藏然后显示。
list.setOnItemClickListener(new AdapterView.OnItemClickListener()
{
@Override
public void onItemClick(AdapterView<?> arg0, View arg1,
int position, long arg3)
{
if(baglanti.DegerDogruMu() == true)
{
ekvar = true; **// If true there is an attachment**
gelen = baglanti.EkinIsmi();
}
else
{
ekvar = false; **// False = no attachment**
}
}
然后我把结果放在意图中。
final Intent intent = new Intent(ListeleActivity.this, GoruntuleActivity.class);
intent.putExtra(ekvarmı, ekvar);
startActivity(intent);
另一个活动调用这个方法来添加“ekvar”
public void ListOnClicklendiginde(final int position , ArrayList<String> bodyliste , ArrayList<String> kimdenlist , ArrayList<String> konulist, boolean ekvarmı , ArrayList<String> ekinismi)
{
**// First I hide the "attachment things"**
dosyaAdi.setVisibility(View.INVISIBLE);
atacResim.setVisibility(View.INVISIBLE);
ekButton.setVisibility(View.INVISIBLE);
**// If there is an attachment then visible the things. (I debug for the no attachment email and it fall the false so the statement is working ok)**
if( ekvarmı == true)
{
dosyaAdi.setVisibility(View.VISIBLE);
atacResim.setVisibility(View.VISIBLE);
ekButton.setVisibility(View.VISIBLE);
}
else
{
dosyaAdi.setVisibility(View.INVISIBLE);
atacResim.setVisibility(View.INVISIBLE);
ekButton.setVisibility(View.INVISIBLE);
}
}

红色方块在图片上他们必须隐藏
