View.Invisible - 图像在屏幕上停留 [英] View.Invisible - images stay on the screen

问题描述

我想设置我的ImageView，按钮及TextView中的知名度。但是，他们还在那里当我运行该程序。
我试过View.GONE但只是删除所有的TextView，ImageView的和按钮。但我只是想隐藏，然后显示出来。

I trying to set visibility of my imageview , button and textview. But they still there when I run the program. I tried the View.GONE but that just remove all the textview, imageview and button. But I just want to hide and then show.

               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，我把结果在意向。

final Intent intent = new Intent(ListeleActivity.this, GoruntuleActivity.class);
intent.putExtra(ekvarmı, ekvar);
startActivity(intent);

与其他活动
调用此方法与添加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);
                }
                 }

XML：

<RelativeLayout
        android:id="@+id/ekTablo"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_x="8dp"
        android:layout_y="102dp" >

        <ImageView
            android:id="@+id/imageViewAttachment"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentLeft="true"
            android:layout_alignParentTop="true"
            android:src="@drawable/ic_email_attachment" />

        <TextView

        <ImageButton

            android:layout_toRightOf="@+id/dosyaAdi"
            android:src="@drawable/ic_indir" />

    </RelativeLayout>

推荐答案

尽量使你的意见的在XML无形并修改Java code这样的

Try to made your views invisible in XML and change your Java code like this

if( ekvarmı == true)
            {
                dosyaAdi.setVisibility(View.VISIBLE);
                atacResim.setVisibility(View.VISIBLE);
                ekButton.setVisibility(View.VISIBLE);

            }
