如何在列表中显示生成的密码

Question

btnGenerateNums.setOnClickListener(new View.OnClickListener() {

            @Override
        public void onClick(View v) {
            tvGeneratedNums.setText("");
            tvResultInTextView.setVisibility(View.GONE);
            tvResultInListView.setVisibility(View.GONE);
            mList.clear();
            if(isValid())
                {
                tvResultInTextView.setVisibility(View.VISIBLE);
                tvResultInListView.setVisibility(View.VISIBLE);
                RandomNumGenerator mRandomNumGen = new RandomNumGenerator(start,end);
                for(int i=0;i<=end-start;i++)
                         {

                    int k = mRandomNumGen.generateNewRandom(i);

                    mList.add(k);

                }
                if(tvGeneratedNums.getText().toString().endsWith(","))
                {
                    tvGeneratedNums.setText(tvGeneratedNums.getText().toString().substring(0, tvGeneratedNums.getText().toString().length()-1));
                }

            }
            mAdapter = new ArrayAdapter<Integer>(mContext, android.R.layout.simple_list_item_1, mList);
            lvGeneratedNums.setAdapter(mAdapter);


            }
    });

我想在列表视图中显示我生成的密码，所以我写了这个，但这只给我一个这样的数字

3

5

10

6

9

8

但我想要的是

3 5 10 6 9 8

8 10 6 9 3 5

5 10 9 8 3 6

9 5 6 10 3 8

等等...

你只需要循环生成更多你想要的数字，这里有一些代码：

btnGenerateNums.setOnClickListener(new View.OnClickListener() {

    @Override
    public void onClick(View v) {
        tvGeneratedNums.setText("");
        tvResultInTextView.setVisibility(View.GONE);
        tvResultInListView.setVisibility(View.GONE);
        mList.clear();

        if(isValid())
            {
            tvResultInTextView.setVisibility(View.VISIBLE);
            tvResultInListView.setVisibility(View.VISIBLE);
            RandomNumGenerator mRandomNumGen = new RandomNumGenerator(start,end);
            for(int i=0;i<=end-start;i++) {
                String randPass = "";
                for(int j=0;j<=5;j++) {
                    int ch = mRandomNumGen.generateNewRandom(i);
                    randPass += " " +String.valueOf(ch);
                }
                mList.add(randPass);
            }
            if(tvGeneratedNums.getText().toString().endsWith(","))
            {
                tvGeneratedNums.setText(tvGeneratedNums.getText().toString().substring(0, tvGeneratedNums.getText().toString().length()-1));
            }

        }
        mAdapter = new ArrayAdapter<Integer>(mContext, android.R.layout.simple_list_item_1, mList);
        lvGeneratedNums.setAdapter(mAdapter);


        }
});

with mList is List;，我不测试这段代码，只是给你一个选项。
