如何从arraylist动态添加textview？

Question

Is it possible add textView in a relative layout dynamically, taking the information from an arraylist? I'll explain. For example I have a arralist with five words that I get from a database. I would then create 5 different textView in its layout. I can not use a listview because it is the user to choose the poszione of these TextView.

This is the code I was working, so I was able to create more TextView, but not from the array list. I also need to give different values ​​for the top margin at each TextView!

RelativeLayout rl = (RelativeLayout) findViewById(R.id.sundayRelativeLayout);
    TextView iv;
    RelativeLayout.LayoutParams params;

    

    float d = this.getResources().getDisplayMetrics().density;

    iv = new TextView(this);
    iv.setBackgroundColor(Color.YELLOW);
    int marginTopDip = 180; // margin in dips
    int marginHeightDips = 60; // margin in dips

    int height = (int)(marginHeightDips * d);
    int margintop = (int)(marginTopDip * d);
    params = new RelativeLayout.LayoutParams(500, height);
    params.topMargin = margintop;
    rl.addView(iv, params);



    iv = new TextView(this);
    iv.setBackgroundColor(Color.RED);
    params = new RelativeLayout.LayoutParams(30, 40);
    params.topMargin = 900;
    rl.addView(iv, params);

Answer 1

Create like this

ArrayList<Integer> list=new ArrayList<Integer>();

if your list size is 5

for(int i=0;i<list.size();i++){
TextView tv=new TextView(this);
tv.setText(""+list.get(i));
}

Answer 2

final int N = 10; // total number of textviews to add

final TextView[] myTextViews = new TextView[N]; // create an empty array;

for (int i = 0; i < N; i++) {
    // create a new textview
    final TextView rowTextView = new TextView(this);

    // set some properties of rowTextView or something
    rowTextView.setText("This is row #" + i);

    // add the textview to the linearlayout
    myLinearLayout.addView(rowTextView);

    // save a reference to the textview for later
    myTextViews[i] = rowTextView;
}

Answer 3

Yeah you can add textview to the relative layout like this.

RelativeLayout container = (RelativeLayout) findViewById(R.id.container);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
                        ViewGroup.LayoutParams.WRAP_CONTENT);

    ArrayList<Integer> list=new ArrayList<Integer>();

    for(int i=0;i<list.size();i++){
       TextView textView = new TextView(this);
       textView1.setText("A"+i);
       textView1.setId(i);
       container.addView(textView);
       params.addRule(RelativeLayout.BELOW,i);      
    }
