添加textviews动态地RelativeLayout的。 [英] Adding textviews dynamically to relativelayout.

问题描述

虽然我加入textviews相对布局，在第一行的末尾，TextView的是走错了。

While I am adding textviews to relative layout, at the end of first line, the textview is going wrong.

，如下面的：

这是我的code到diplay textviews。

here is my code to diplay textviews.

public void showkeyword()
{
    LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    RelativeLayout fl =  (RelativeLayout)findViewById(R.id.key_layout); 
    fl.removeAllViews();
    RelativeLayout.LayoutParams params ;

        //TextView key = (TextView) inflater.inflate(R.layout.tag_keyword,null);

i = 0;

   for(String s : alist)
   {   
        TextView textview = (TextView) inflater.inflate(R.layout.tag_keyword,null);
        textview.setText(s);
        textview.setId(2000 + i);      

        if (i == 0) {
            RelativeLayout.LayoutParams rlp2 = new RelativeLayout.LayoutParams(
                    RelativeLayout.LayoutParams.WRAP_CONTENT,
                    RelativeLayout.LayoutParams.WRAP_CONTENT);
            rlp2.addRule(RelativeLayout.ALIGN_PARENT_TOP);
            rlp2.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
            textview.setLayoutParams(rlp2);
            fl.addView(textview);

        } else {
            RelativeLayout.LayoutParams rlp2 = new RelativeLayout.LayoutParams(
                    RelativeLayout.LayoutParams.WRAP_CONTENT,
                    RelativeLayout.LayoutParams.WRAP_CONTENT);
           // rlp2.addRule(RelativeLayout.ALIGN_BASELINE);
            rlp2.setMargins(10,0, 10,0);
            rlp2.addRule(RelativeLayout.RIGHT_OF, textview.getId() - 1);
            textview.setLayoutParams(rlp2);
            fl.addView(textview);  
        }          
       i++;
   }

}

我想有这样的事情，形式的标签实现：

I wish to have something like this, sort of a tab implementation:

希望下面的code会帮助你：

运作

contactWrapper是线性的布局，我们继续添加textviews到这些线性布局逐个和之前加入找到contactWrapper是否具有空间足以把在接下来的TextView，如果创建不是一个新的线性布局和textViews被添加进去了。

contactWrapper is a linear layout, we go on adding the textviews into these linear layouts one by one and before adding find whether the contactWrapper has space enough to put in the next TextView, if not a new linear layout is created and the textViews are added into it.

花时间分析如下code。

Take time analyzing the following code.

public void drawLayout() {
    int counter = 0;
    contactWrapperWidth = getResources().getDisplayMetrics().widthPixels;
    contactWrapper.setOrientation(LinearLayout.VERTICAL); 
    // contact wrapper is a linear Layout 
    // use LinearLayout contactWrapper = (LinearLayout) mView
    //          .findViewById(R.id.yourLinearLayout);
    currCounter = 0;
    currWidth = 0;
    isNewLine = false;

    row[currCounter] = new LinearLayout(getActivity());

    @SuppressWarnings("rawtypes")
    Iterator it = button.iterator();

    for (int i = 0; i < button.size(); i++) {
        it.next();
        row[currCounter].setLayoutParams(new LinearLayout.LayoutParams(
                LinearLayout.LayoutParams.MATCH_PARENT,
                LinearLayout.LayoutParams.WRAP_CONTENT));
        currWidth += Integer
                .parseInt(button.get(i).get("width").toString());
        Log.i("Item width ", "i == "
                + button.get(i).get("width").toString());

        // contactWrapper.getw

        if (isNewLine) {
            if (currWidth < contactWrapperWidth) {
                row[currCounter]
                        .addView((View) button.get(i).get("button"));
                if (!it.hasNext()) {
                    contactWrapper.addView(row[currCounter]);
                } else {
                    if (contactWrapperWidth < (currWidth + Integer
                            .parseInt(button.get(i + 1).get("width")
                                    .toString()))) {
