java如何对ListView中的每个位置执行不同的操作？

Question

我想为ListView中的每一项做一个不同的操作（可能是意图），而不是Toast，谢谢

这是我的java代码

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        // Array of strings...
        final String[] mobileArray = {"Android", "IPhone", "WindowsMobile", "Blackberry",
                "WebOS", "Ubuntu", "Windows7", "Max OS X"};


        final ArrayAdapter adapter = new ArrayAdapter<String>(this,
                R.layout.activity_listview, mobileArray);

        final ListView listView = (ListView) findViewById(R.id.listView);
        listView.setAdapter(adapter);

        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> a, View v, int position,
                                    long id) {
                Toast.makeText(MainActivity.this, "hello world", Toast.LENGTH_SHORT).show();


                }
            });
     }
}

使用position在listView的不同行上执行不同的操作。Setonic就是这样的听众

    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> a, View v, int position,
                            long id) {
       switch (position){
             case 0:
             // your code here
             break;
             case 1:
             // your code
             break;
             ..... so on
        }


        }
    });

您可以创建一个函数，将recive position作为它的参数

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
                                            @Override
                                            public void onItemClick(AdapterView<?> a, View v, int position,
                                                                    long id) {

                                                doSomething(position);

                                            }
                                            public void doSomething(int position){

                                                switch(position)
                                                {
                                                    case 1:
                                                        //do this
                                                        break;
                                                    case 2:
                                                        //do this
                                                    break;
                                                }
                                            }});
