            android:layout_height="fill_parent"

Custom item for ListVIew:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:background="#fff" >
        <TextView
            android:id="@+id/textViewTimeResult"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="Large Text"
            android:textAppearance="?android:attr/textAppearanceLarge"
            android:textColor="#000000" />

        <TextView
            android:id="@+id/textViewTimeResult2"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="Large Text"
            android:textAppearance="?android:attr/textAppearanceLarge"
            android:textColor="#000000"/>
    </LinearLayout>

告诉我我怎么能在OnCreate隐藏textViewTimeResult2。
如果我写：

Show me how I can hide textViewTimeResult2 in the onCreate. If I write:

TextView test = (TextView) findById(R.id.textViewTimeResult2);
test.setVisibility(TextView.GONE);

我的程序开始崩溃了。

My program crashed in start.

推荐答案

在您的适配器可以试试这个code隐藏第二TextView的。

In your adapter you can try this code to hide the second textview.

public View getView(int position, View convertView, ViewGroup parent){
       convertView = mInflater.inflate(R.layout.your_custom_list_layout, null);
    TextView textOne = (TextView)convertView.findViewById(R.id.txtOne);
    TextView textTwo = (TextView)convertView.findViewById(R.id.txtTwo);

    textTwo.setVisibility(View.GONE);

    return convertView;
} 

新增：
您可以添加内部切换一个布尔你的的onClick（）再修改 getView（）;

    boolean hideTextTwo = false;

    onClick(View v){
      hideTextTwo = true;
      yourAdapter.notifyDatasetChanged();

    }


public View getView(int position, View convertView, ViewGroup parent){
    convertView = mInflater.inflate(R.layout.your_custom_list_layout, null);
    TextView textOne = (TextView)convertView.findViewById(R.id.txtOne);
    TextView textTwo = (TextView)convertView.findViewById(R.id.txtTwo);

if(hideTextTwo){
    textTwo.setVisibility(View.GONE);
}

    return convertView;
}
