安卓listview使用的一種方法

先上個效果圖

溫度報警設置是用listview容器裝載。包含兩個textview和兩個button。

首先，聲明兩個必要組建，ListView和ArrayList是兩個必要的容器

private ListView listView;
private ArrayList<String> data = new ArrayList<>();

listview的初始化處理

listView = (ListView)findViewById(R.id.alert_setting_list);
generateListContent();
listView.setAdapter(new MyListAdapter(this,R.layout.alert_setting_item,data));

generateListContent的實現

private void generateListContent(){
    for (int i = 0; i < 3; i++) {
        data.add("This is no " + i);
    }
}

MyListAdapter的實現

private class MyListAdapter extends ArrayAdapter<String> {

        private int layout;
        public MyListAdapter(Context context, int resource, List<String> objects) {
            super(context, resource, objects);
            layout = resource;
        }

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            ViewHolder mainViewHolder = null;
            if (convertView == null){
                LayoutInflater layoutInflater = LayoutInflater.from(getContext());
                convertView = layoutInflater.inflate(layout, parent, false);
                final ViewHolder viewHolder = new ViewHolder();
                viewHolder.textTitle = (TextView)convertView.findViewById(R.id.setting_title);
                viewHolder.addButton = (Button)convertView.findViewById(R.id.add_button);
                viewHolder.textContent = (TextView)convertView.findViewById(R.id.setting_content);
                viewHolder.minusButton = (Button)convertView.findViewById(R.id.minus_button);
                switch (position){
                    case 0:
                        viewHolder.textTitle.setText("高溫報警線");
                        viewHolder.textContent.setText("38.0");
                        viewHolder.addButton.setOnClickListener(new View.OnClickListener() {
                            @Override
                            public void onClick(View v) {
                                //在這裏添加對按鈕點擊的響應事件
                            }
                        });

                        viewHolder.minusButton.setOnClickListener(new View.OnClickListener() {
                            @Override
                            public void onClick(View v) {
                                //在這裏添加對按鈕點擊的響應事件
                            }
                        });
                        break;
                    case 1:
                        viewHolder.textTitle.setText("低溫報警線");
                        viewHolder.textContent.setText("36.0");
                        viewHolder.addButton.setOnClickListener(new View.OnClickListener() {
                            @Override
                            public void onClick(View v) {
                                //在這裏添加對按鈕點擊的響應事件
                            }
                        });

                        viewHolder.minusButton.setOnClickListener(new View.OnClickListener() {
                            @Override
                            public void onClick(View v) {
                                //在這裏添加對按鈕點擊的響應事件
                            }
                        });
                        break;
                    case 2:
                        viewHolder.textTitle.setText("間隔時間");
                        viewHolder.textContent.setText(String.valueOf(10));
                        viewHolder.addButton.setOnClickListener(new View.OnClickListener() {
                            @Override
                            public void onClick(View v) {
                                //在這裏添加對按鈕點擊的響應事件
                            }
                        });

                        viewHolder.minusButton.setOnClickListener(new View.OnClickListener() {
                            @Override
                            public void onClick(View v) {
                                //在這裏添加對按鈕點擊的響應事件
                            }
                        });
                        break;
                    default:
                        break;
                }

                convertView.setTag(viewHolder);
            }else{
                mainViewHolder = (ViewHolder)convertView.getTag();
            }
            return convertView;
        }
    }

    public class ViewHolder{
        TextView textTitle;
        Button addButton;
        TextView textContent;
        Button minusButton;
    }

這樣就能基本完成一個listview的界面，當然listview的實現方法不止這一種，僅提供一種參考，歡迎討論。代碼資源：http://download.csdn.net/detail/will4906/9657851
