安卓：添加textViews在RelativeLayout的编程方式 [英] Android: Add textViews in RelativeLayout Programatically

问题描述

我有一个RelativeLayout的，我想插入一些textViews。

I have an RelativeLayout and I would like to insert some textViews.

下面是code：

 <RelativeLayout
    android:id="@+id/JournalSearchListView"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:minHeight="30dp"
    android:layout_below="@+id/JournalsSearchTextView"
    android:orientation="vertical" 
    android:cacheColorHint="#00000000">

    <ProgressBar
        android:id="@+id/JournalSearchProgressBar"
        style="?android:attr/progressBarStyleSmall"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true" />

</RelativeLayout>

和我如何做这个编程方式：

And how I am doing this programatically:

RelativeLayout journals = (RelativeLayout) findViewById(R.id.JournalSearchListView);
RelativeLayout.LayoutParams params1 = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);  
for (int i=0;i< authorNames.size();i++) {
    TextView tv = new TextView(this);
    tv.setId(i); 
    tv.setText(authorNames.get(i));
    tv.setTextColor(Color.BLACK);
    Integer a = tv.hashCode();
    map.put(a,authorNames.get(i));
    params1.addRule(RelativeLayout.BELOW, tv.getId());
    journals.addView(tv, params1);
    tv.setOnClickListener(new OnClickListener() {
         public void onClick(View v) {
             System.out.println("Clicked "+ map.get(v.hashCode()) );    
         }
    });   
}

但问题是，每个TextView的是在相同的位置等。

But the problem is that each textView is in the same position as the others.

推荐答案

params1.addRule（RelativeLayout.BELOW，tv.getId（））;

正在将其设置为自己下面？
如果你希望他们下面的海誓山盟做这种方式：

You are setting it to be below itself?
If you want them below eachother do it this way:

RelativeLayout journals = (RelativeLayout) findViewById(R.id.JournalSearchListView);
LinearLayout lL = new LinearLayout(context);
lL.setOrientation(LinearLayout.VERTICAL);

   for (int i=0;i< authorNames.size();i++) {
     TextView tv = new TextView(this);
     tv.setId(i); 
     tv.setText(authorNames.get(i));
         tv.setTextColor(Color.BLACK);
         Integer a = tv.hashCode();
         map.put(a,authorNames.get(i));
         if(i!=0)
         params1.addRule(RelativeLayout.BELOW, i-1);
         tv.setOnClickListener(new OnClickListener() {
           public void onClick(View v) {
           System.out.println("Clicked "+ map.get(v.hashCode()) ); 
       }
   });
         lL.addView(tv);   
 }
journals.addview(lL);
