动态地添加按钮中的RelativeLayout到的LinearLayout [英] Adding Buttons dynamically in RelativeLayout to LinearLayout

问题描述

当用户输入一个字，他创造了许多按钮等于字的长度。例如：如果用户输入AAAA他将边创建4个按钮，边，第一排。然后，如果用户输入BB，他将创造2 按钮，并排，第二排。和CCC他创造了3 按钮 ...

图像来演示：

我动态创建一个 RelativeLayout的，然后动态地添加按钮到布局。最后我想补充 RelativeLayout的来我现有的的LinearLayout 。但问题是，只有一个按钮是每行补充说。而我的计划目前看起来是这样的：

有人请我解决这个问题？

code：

 最后的LinearLayout的LinearLayout =（的LinearLayout）findViewById（R.id.ll_bttn_words）;    最后LinearLayout.LayoutParams LLP =新LinearLayout.LayoutParams（
            LayoutParams.WRAP_CONTENT，
            LayoutParams.WRAP_CONTENT）;    button_test.setOnClickListener（
            新View.OnClickListener（）
            {
                公共无效的onClick（查看视图）
                {
                    的RelativeLayout的RelativeLayout =新的RelativeLayout（view.getContext（））;                    RelativeLayout.LayoutParams RLP =新RelativeLayout.LayoutParams（
                                    RelativeLayout.LayoutParams.WRAP_CONTENT，
                                    RelativeLayout.LayoutParams.WRAP_CONTENT）;
                    INT大小= enter_txt.getText（）的toString（）长（）。 //按钮的用户输入的数目                    INT ID = 1;                    的for（int i = 0; I＆LT;大小;我++）
                    {
                        按钮myButton的=新按钮（view.getContext（））;                        myButton.setBackgroundResource（R.drawable.button）;                        myButton.setId（ID）;                        rlp.addRule（RelativeLayout.RIGHT_OF，myButton.getId（））;                        relativeLayout.addView（myButton的，RLP）;                        ID ++;
                    }                        linearLayout.addView（RelativeLayout的，LLP）;
 

解决方案

  rlp.addRule（RelativeLayout.RIGHT_OF，myButton.getId（））;
 

该行表示，为myButton应添加到myButton的权利，这没有任何意义。

要解决这个简单的方法是使用下面的行，而不是

  rlp.addRule（RelativeLayout.RIGHT_OF，myButton.getId（） -  1）;
 

但是，这不是要做到这一点的最好办法，你应该使用的LinearLayout与水平方向相反。

When the user inputs a word, he creates a number of Buttons equal to the length of the word. For example: if user inputs "aaaa" he will create 4 Buttons, side by side, in the first row. Then if the user enters "bb" he will create 2 Buttons, side by side, in the second row. And "ccc" he creates 3 Buttons...

Image to demonstrate:

I dynamically create a RelativeLayout, then dynamically add Buttons to that layout. And finally I add the RelativeLayout to my existing LinearLayout. But the problem is, only one Button is added per row. And my program currently looks like this:

Can someone please me fix this problem?

CODE:

    final LinearLayout linearLayout = (LinearLayout) findViewById(R.id.ll_bttn_words);

    final LinearLayout.LayoutParams llp = new LinearLayout.LayoutParams(
            LayoutParams.WRAP_CONTENT,
            LayoutParams.WRAP_CONTENT);

    button_test.setOnClickListener(
            new View.OnClickListener()
            {
                public void onClick(View view)
                {
                    RelativeLayout relativeLayout = new RelativeLayout(view.getContext());

                    RelativeLayout.LayoutParams rlp = new RelativeLayout.LayoutParams(
                                    RelativeLayout.LayoutParams.WRAP_CONTENT,
                                    RelativeLayout.LayoutParams.WRAP_CONTENT);    


                    int size = enter_txt.getText().toString().length(); //the user input number of buttons

                    int id = 1;

                    for (int i=0; i<size; i++)
                    {
                        Button myButton = new Button(view.getContext());

                        myButton.setBackgroundResource(R.drawable.button);

                        myButton.setId(id);

                        rlp.addRule(RelativeLayout.RIGHT_OF, myButton.getId());

                        relativeLayout.addView(myButton, rlp);

                        id++;
                    }

                        linearLayout.addView(relativeLayout, llp);

解决方案

rlp.addRule(RelativeLayout.RIGHT_OF, myButton.getId());

This line says that myButton should be added to right of myButton, which doesn't make any sense.

simple way to resolve this is to use the following line instead

rlp.addRule(RelativeLayout.RIGHT_OF, myButton.getId()-1);

But this isn't the best way to do this, you should use LinearLayout with horizontal orientation instead.
