Android的佈局需要幫助

我想要做的是有兩個微調和低於一個按鈕，一旦單擊該按鈕時，我展示成果的基礎上在紡紗機中選擇的值。

----------- 
| Spinner 1 |  
----------- 
----------- 
| Spinner 2 |  
----------- 
----------- 
| Button |  
----------- 

Result 1 
Result 2 
Result 3 
Result 4 
Result 5

我試圖把結果在ListView，但我面對的問題是，一旦點擊按鈕時，我可以看到Spinner1，Spinner2的重複和多次按鈕本身。

佈局的XML如下：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent" 
android:orientation="vertical" > 

<Spinner 
    android:id="@+id/spinner1" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:entries="@array/country_arrays" 
    android:prompt="@string/country_prompt" />  

    <Spinner 
    android:id="@+id/spinner2" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:entries="@array/country_arrays" 
    android:prompt="@string/country_prompt" /> 

<Button 
    android:id="@+id/button1" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="@string/done" /> 

<LinearLayout 
    android:id="@+id/moreContent" 
    android:layout_width="match_parent" 
    android:visibility="visible" 
    android:orientation="vertical"  
    android:layout_height="wrap_content"  
    > 

<ListView 
    android:id="@android:id/list" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    /> 

<TextView 
    android:id="@+id/textView2" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="@string/hello_world" 
    android:textColor="#ff0000" 
    android:textSize="12sp" /> 

<TextView 
    android:id="@+id/textView1" 
    android:layout_width="wrap_content" 
    android:layout_height="fill_parent" 
    android:contentDescription="@string/hello_world" 
    android:gravity="center_vertical" 
    android:text="@string/hello_world" 
    android:textColor="#0000ff" 
    android:textSize="12sp" /> 
</LinearLayout>

可有人請告知我要去哪裏錯了？

    public void set_line(String _line) { 
     this._line = _line;

適配器如下：

package ms.timetable; 

import java.util.ArrayList; 
import ms.timetable.MainActivity.TimeTable; 

import android.content.Context; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.ArrayAdapter; 
import android.widget.TextView; 

public class TimetableAdapter extends ArrayAdapter<TimeTable>{ 
private final Context context; 
private final ArrayList<TimeTable> values; 

public TimetableAdapter(Context context, ArrayList<TimeTable> values){ 
    super(context, R.layout.activity_main, values); 
    this.context = context; 
    this.values = values; 
} 

public View getView(int position, View convertView, ViewGroup parent) { 
    LayoutInflater inflater = (LayoutInflater) context 
      .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 

    View rowView = inflater.inflate(R.layout.activity_main, parent, false); 
    TextView textView = (TextView) rowView.findViewById(R.id.textView1); 
    TextView textView2 = (TextView) rowView.findViewById(R.id.textView2); 

    //System.err.println("Position is : "+position); 
    TimeTable tt = values.get(position); 
    textView.setText(tt.get_departure()); 
    textView2.setText(tt.get_arrival()); 
    return rowView; 
} 

}

我想我們需要看你的代碼，也不理解'textView1'和'textView2'的作用。不過，我認爲你的'LinearLayout'看起來不錯。 – 2013-04-09 05:10:09

我已編輯帖子並添加了代碼。謝謝。 – user2260040 2013-04-09 06:20:20

的問題是由於

View rowView = inflater.inflate(R.layout.activity_main, parent, false);

在getView()方法。

你正在充滿整個activity_main在一行，然後將其添加到列表視圖。將結果放在單獨的xml中而不是activity_main中。所以，你將有一個新的XML文件說，row.xml其中將包含：

<TextView 
    android:id="@+id/textView2" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="@string/hello_world" 
    android:textColor="#ff0000" 
    android:textSize="12sp" /> 

<TextView 
    android:id="@+id/textView1" 
    android:layout_width="wrap_content" 
    android:layout_height="fill_parent" 
    android:contentDescription="@string/hello_world" 
    android:gravity="center_vertical" 
    android:text="@string/hello_world" 
    android:textColor="#0000ff" 
    android:textSize="12sp" />

所以，你將不得不誇大爲

View rowView = inflater.inflate(R.layout.row, parent, false);

，然後添加在這是在列表視圖生成的行activity_main.xml中。所以你的問題將得到解決。希望能幫助到你。
