为ListView的多行中的多个TextView设置onClickListener [英] Set onClickListener for multiple TextView's in multiple rows of a ListView

问题描述

我已经从ArrayList<ArrayList<String>>设置了一个名为ListView的数据，该数据看起来像这样

data = {{"cat1","cat2","cat3","cat4"},
                      {"dog1","dog2","dog3"},
                      {"lion1"},
                      {"monkey1","monkey2"}};

我将其设置如下:

public static final String[] weekdayStringArray = {"Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"};

@Override
    public View getView(int position, View convertView, ViewGroup parent) {
         ArrayList<String> stringArrayList = data.get(position);
         String dayString = weekdayStringArray[dayNumber];

         switch(stringArrayList.size()){
            case 4:
                convertView = mLayoutInflater.inflate(R.layout.four_meal_item_view, parent, false);
                TextView mealOne_Four = (TextView) convertView.findViewById(R.id.firstMealTextView);
                TextView mealTwo_Four = (TextView) convertView.findViewById(R.id.secondMealTextView);
                TextView mealThree_Four = (TextView) convertView.findViewById(R.id.thirdMealTextView);
                TextView mealFour_Four = (TextView) convertView.findViewById(R.id.fourthMealTextView);
                TextView dayText_Four = (TextView) convertView.findViewById(R.id.dayTextView);
                dayText_Four.setText(dayString);
                mealOne_Four.setText(stringArrayList.get(0).substring(0,1).toUpperCase() + stringArrayList.get(0).substring(1).toLowerCase());
                mealTwo_Four.setText(stringArrayList.get(1).substring(0,1).toUpperCase() + stringArrayList.get(1).substring(1).toLowerCase());
                mealThree_Four.setText(stringArrayList.get(2).substring(0,1).toUpperCase() + stringArrayList.get(2).substring(1).toLowerCase());
                mealFour_Four.setText(stringArrayList.get(3).substring(0,1).toUpperCase() + stringArrayList.get(3).substring(1).toLowerCase());
                break;
            case 3:
                convertView = mLayoutInflater.inflate(R.layout.three_meal_item_view, parent, false);
                TextView mealOne_Three = (TextView) convertView.findViewById(R.id.firstMealTextView_Three);
                TextView mealTwo_Three = (TextView) convertView.findViewById(R.id.secondMealTextView_Three);
                TextView mealThree_Three = (TextView) convertView.findViewById(R.id.thirdMealTextView_Three);
                TextView dayText_Three = (TextView) convertView.findViewById(R.id.dayTextView_Three);
                dayText_Three.setText(dayString);
                mealOne_Three.setText(stringArrayList.get(0).substring(0,1).toUpperCase() + stringArrayList.get(0).substring(1).toLowerCase());
                mealTwo_Three.setText(stringArrayList.get(1).substring(0,1).toUpperCase() + stringArrayList.get(1).substring(1).toLowerCase());
                mealThree_Three.setText(stringArrayList.get(2).substring(0,1).toUpperCase() + stringArrayList.get(2).substring(1).toLowerCase());
                break;
            case 2:
                convertView = mLayoutInflater.inflate(R.layout.two_meal_item_view, parent, false);
                TextView mealOne_Two = (TextView) convertView.findViewById(R.id.firstMealTextView_Two);
                TextView mealTwo_Two = (TextView) convertView.findViewById(R.id.secondMealTextView_Two);
                TextView dayText_Two = (TextView) convertView.findViewById(R.id.dayTextView_Two);
                dayText_Two.setText(dayString);
                mealOne_Two.setText(stringArrayList.get(0).substring(0,1).toUpperCase() + stringArrayList.get(0).substring(1).toLowerCase());
                mealTwo_Two.setText(stringArrayList.get(1).substring(0,1).toUpperCase() + stringArrayList.get(1).substring(1).toLowerCase());
                break;
            case 1:
                convertView = mLayoutInflater.inflate(R.layout.one_meal_item_view, parent, false);
                TextView mealOne_One = (TextView) convertView.findViewById(R.id.firstMealTextView_One);
                TextView dayText_One = (TextView) convertView.findViewById(R.id.dayTextView_One);
                dayText_One.setText(dayString);
                mealOne_One.setText(stringArrayList.get(0).substring(0,1).toUpperCase() + stringArrayList.get(0).substring(1).toLowerCase());
                break;
            case 0:
                convertView = mLayoutInflater.inflate(R.layout.zero_meal_item_view, parent, false);
                TextView dayText_Zero = (TextView) convertView.findViewById(R.id.dayTextView_Zero);
                dayText_Zero.setText(dayString + "(Closed)");
                break;
         }
return convertView;

现在我想添加一个onClickListener，以便可以连续单击一个TextView.当单击此TextView时，我将移至新的Activity，并传递所单击的TextView的文本和与所单击的TextView在同一行的dayTextView的文本.

现在，我不想为每个TextView设置一堆onClickListners，那么对我行中的所有TextView执行此操作的有效方法是什么? ListView?

解决方案

选项1:

在每个textView的xml中，将onClick设置为相同的方法

android:onClick= "itemtapped"

然后在您的活动中点击呼叫项，并让其获得textview名称和位置编号，这样您就可以知道哪一个被点击了.

选项2:

在接受所窃取物品的活动中进行自定义功能

类似这样的东西

       public void setOnClickListener(TextView... arrayOfView, int position){

     TextView[] ]textViewArray = textViewArray;

    for(int i = 0 ; i < textViewArray.length ; ++i){

        int index = i; 
        textViewArray[i].setOnClickListener(new OnClickListener(){

                @Override
                public void onClick(View v){
                     Intent intent = new Intent(MainActivity.this, YourTargetActivity.class);
                     startActivity(intent);
                     int textViewNumber = position;

                }
        });
    }

然后传递位置，这样您就知道它是什么，并且知道该行中的textview

快乐编码:)

I have set up a ListView from an ArrayList<ArrayList<String>> called data of data that looks like this

data = {{"cat1","cat2","cat3","cat4"},
                      {"dog1","dog2","dog3"},
                      {"lion1"},
                      {"monkey1","monkey2"}};

And I have set it up like this:

public static final String[] weekdayStringArray = {"Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"};

@Override
    public View getView(int position, View convertView, ViewGroup parent) {
         ArrayList<String> stringArrayList = data.get(position);
         String dayString = weekdayStringArray[dayNumber];

         switch(stringArrayList.size()){
            case 4:
                convertView = mLayoutInflater.inflate(R.layout.four_meal_item_view, parent, false);
                TextView mealOne_Four = (TextView) convertView.findViewById(R.id.firstMealTextView);
                TextView mealTwo_Four = (TextView) convertView.findViewById(R.id.secondMealTextView);
                TextView mealThree_Four = (TextView) convertView.findViewById(R.id.thirdMealTextView);
                TextView mealFour_Four = (TextView) convertView.findViewById(R.id.fourthMealTextView);
                TextView dayText_Four = (TextView) convertView.findViewById(R.id.dayTextView);
                dayText_Four.setText(dayString);
                mealOne_Four.setText(stringArrayList.get(0).substring(0,1).toUpperCase() + stringArrayList.get(0).substring(1).toLowerCase());
                mealTwo_Four.setText(stringArrayList.get(1).substring(0,1).toUpperCase() + stringArrayList.get(1).substring(1).toLowerCase());
                mealThree_Four.setText(stringArrayList.get(2).substring(0,1).toUpperCase() + stringArrayList.get(2).substring(1).toLowerCase());
                mealFour_Four.setText(stringArrayList.get(3).substring(0,1).toUpperCase() + stringArrayList.get(3).substring(1).toLowerCase());
                break;
            case 3:
                convertView = mLayoutInflater.inflate(R.layout.three_meal_item_view, parent, false);
                TextView mealOne_Three = (TextView) convertView.findViewById(R.id.firstMealTextView_Three);
                TextView mealTwo_Three = (TextView) convertView.findViewById(R.id.secondMealTextView_Three);
                TextView mealThree_Three = (TextView) convertView.findViewById(R.id.thirdMealTextView_Three);
                TextView dayText_Three = (TextView) convertView.findViewById(R.id.dayTextView_Three);
                dayText_Three.setText(dayString);
                mealOne_Three.setText(stringArrayList.get(0).substring(0,1).toUpperCase() + stringArrayList.get(0).substring(1).toLowerCase());
                mealTwo_Three.setText(stringArrayList.get(1).substring(0,1).toUpperCase() + stringArrayList.get(1).substring(1).toLowerCase());
                mealThree_Three.setText(stringArrayList.get(2).substring(0,1).toUpperCase() + stringArrayList.get(2).substring(1).toLowerCase());
                break;
            case 2:
                convertView = mLayoutInflater.inflate(R.layout.two_meal_item_view, parent, false);
                TextView mealOne_Two = (TextView) convertView.findViewById(R.id.firstMealTextView_Two);
                TextView mealTwo_Two = (TextView) convertView.findViewById(R.id.secondMealTextView_Two);
                TextView dayText_Two = (TextView) convertView.findViewById(R.id.dayTextView_Two);
                dayText_Two.setText(dayString);
                mealOne_Two.setText(stringArrayList.get(0).substring(0,1).toUpperCase() + stringArrayList.get(0).substring(1).toLowerCase());
                mealTwo_Two.setText(stringArrayList.get(1).substring(0,1).toUpperCase() + stringArrayList.get(1).substring(1).toLowerCase());
                break;
            case 1:
                convertView = mLayoutInflater.inflate(R.layout.one_meal_item_view, parent, false);
                TextView mealOne_One = (TextView) convertView.findViewById(R.id.firstMealTextView_One);
                TextView dayText_One = (TextView) convertView.findViewById(R.id.dayTextView_One);
                dayText_One.setText(dayString);
                mealOne_One.setText(stringArrayList.get(0).substring(0,1).toUpperCase() + stringArrayList.get(0).substring(1).toLowerCase());
                break;
            case 0:
                convertView = mLayoutInflater.inflate(R.layout.zero_meal_item_view, parent, false);
                TextView dayText_Zero = (TextView) convertView.findViewById(R.id.dayTextView_Zero);
                dayText_Zero.setText(dayString + "(Closed)");
                break;
         }
return convertView;

And now I want to add an onClickListener so that I can click a TextView in a row. And when this TextView is clicked I move to a new Activitypassing the text of the TextView that was clicked and the text of the dayTextView that was in the same row as the TextView that was clicked.

Now I don't want to set a bunch of onClickListners for each TextView so what is an efficient way of doing this for all the TextViews in the rows of my ListView?

解决方案

Option 1:

In the xml for each textView set the onClick to the same method

android:onClick= "itemtapped"

Then call item tapped in your activity and have it get the textview name and position number so you know which one was tapped.

Option 2:

Make a custom funciton in the activity that takes the item that was tapped

Something like this

       public void setOnClickListener(TextView... arrayOfView, int position){

     TextView[] ]textViewArray = textViewArray;

    for(int i = 0 ; i < textViewArray.length ; ++i){

        int index = i; 
        textViewArray[i].setOnClickListener(new OnClickListener(){

                @Override
                public void onClick(View v){
                     Intent intent = new Intent(MainActivity.this, YourTargetActivity.class);
                     startActivity(intent);
                     int textViewNumber = position;

                }
        });
    }

And then pass in the position so you know what one it is and the textview in that row

Happy Coding :)
