Question

我想在Android上单击ListView项目点击时阅读文本文件.. 我想创建一个Android应用程序，我在其中创建了ListView的一些字符串列表。如果我点击ListView项目，将打开一个文本文件，如何在Android Studio中执行此操作

Answer 1

public void onListItemClick(ListView l, View v, int position, long id) {

您可能需要一个班级Filechooser，您可以将意图发送到

 Intent i = new Intent(this, FileChooser.class);

Answer 2

你可以试试这个：

// Instanciating an array list
ArrayList<String> your_array_list = new ArrayList<String>();
//add file names    

// This is the array adapter, it takes the context of the activity as a 
// first parameter, the type of list view as a second parameter and your 
// array as a third parameter.
ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(
         this, 
         android.R.layout.simple_list_item_1,
         your_array_list );

listview.setAdapter(arrayAdapter); 

listview.setOnItemClickListener(new AdapterView.OnItemClickListener()
{
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id)
    {
        String file_name = your_array_list.get(position);
        File file = new File(dirPath, file_name);
        //do stuff
    }           
});
