<string-array name="ListItem"> 
     <item>Gameplay Intro</item> 
     <item>Enable the Leaderboard System</item> 
     <item>Extra Moves and Features</item> 
     <item>Learn work of Super Jewels </item>

     <item>detail 3</item> 
     <item>detail 4</item> 
     <item>detail 5</item> 
     <item>detail 6</item> 
    </string-array> 

ListActivity代碼：

public class ListActivity extends AppCompatActivity { 
    public static String[] listitems; 
    ListView lvStatus; 
    private NativeExpressAdView nativeExpressAdView; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_list); 
     lvStatus = (ListView)findViewById(R.id.lvStatus); 
     listitems=getResources().getStringArray(R.array.ListItem); 
     ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,listitems); 
     lvStatus.setAdapter(adapter); 
     lvStatus.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
      @Override 
      public void onItemClick(AdapterView<?> adapterView, View view, int position, long id) { 
       Intent intent = new Intent(ListActivity.this,ShowActivity.class); 
       startActivity(intent); 
      } 
     }); 
    } 
} 

說明show活動代碼：

public class ShowActivity extends AppCompatActivity { 
    public static String[] descriptions; 
    TextView tvDetail; 
    String listitems[]; 
    int intposition = 0; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_show); 
     descriptions = getResources().getStringArray(R.array.Description); 
     ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.list_content,descriptions); 
     intposition = getIntent().getIntExtra("position", 0); 
     tvDetail = (TextView) findViewById(R.id.tvDetail); 
     tvDetail.setText((CharSequence) adapter); 
     tvDetail.setMovementMethod(new ScrollingMovementMethod()); 
    } 
} 

Answer 1

您得到的點擊在該方法的位置：

@Override 
     public void onItemClick(AdapterView<?> adapterView, View view, int position, long id) { 
      Intent intent = new Intent(ListActivity.this,ShowActivity.class); 
      startActivity(intent); 
     } 

保存該位置並顯示來自另一個陣列的相同位置的數據。 有很多方法可以做到這一點，其中之一是：

i.putExtra("selected_item", position);
