Question

我在android中非常新。我正在制作一个列表视图，每次我点击列表的项目时它会显示第二个列表视图，但第二个列表视图中的所有项目都不可点击。我已经尝试了所有解决方案，使第二个列表中的项目可以点击，但不适用于我。到目前为止，这是我的代码：

主要活动：

public class MainActivity extends AppCompatActivity {
    String[] boundryitems = {"Boundry Wall","Front Elevation","Corridor","Kitchen","Bedroom1"};

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        //Boundry List Adapter

        final ArrayAdapter boundry_Item1 = new ArrayAdapter<String>(this,
                R.layout.activity_main,R.id.texti, boundryitems);
        ListView listView11 = (ListView) findViewById(R.id.listvi);
        listView11.setAdapter(boundry_Item1);


        listView11.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            public void onItemClick(AdapterView<?> parent, View view,
                                    int position, long id) {
                if (position == 0) {

                    Intent myIntent = new Intent(view.getContext(), item1.class);

                    startActivityForResult(myIntent, 0);

                }
                if (position == 1) {
                    Intent myIntent = new Intent(view.getContext(), item1.class);
                    startActivityForResult(myIntent, 0);

                }

                if (position == 2) {
                    Intent myIntent = new Intent(view.getContext(), item1.class);
                    startActivityForResult(myIntent, 0);
                }

                if (position == 3) {
                    Intent myIntent = new Intent(view.getContext(), item1.class);
                    startActivityForResult(myIntent, 0);
                }

                if (position == 4) {
                    Intent myIntent = new Intent(view.getContext(), item1.class);
                    startActivityForResult(myIntent, 0);
                }

                if (position == 5) {
                    Intent myIntent = new Intent(view.getContext(), item1.class);
                    startActivityForResult(myIntent, 0);
                }

                if (position == 6) {
                    Intent myIntent = new Intent(view.getContext(), item1.class);
                    startActivityForResult(myIntent, 0);
                }

                if (position == 7) {
                    Intent myIntent = new Intent(view.getContext(), item1.class);
                        startActivityForResult(myIntent, 0);
                    }
                }
            });
        }
    }

第1项（包含第二个Listview）：

 public class item1 extends Activity {

        String[] snaglistciv = {"Paint","Garbage Room","Pump Room","Lights","Joint"};
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.snag_item);

    //Snag List Adapter

            final ArrayAdapter adapterSnag_Item = new ArrayAdapter<String>(this,
                    R.layout.snag_item,R.id.textsnag, snaglistciv);

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



            listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
                public void onItemClick(AdapterView<?> parent, View view,
                                        int position, long id) {
                    if (position == 0) {


                        Intent myIntent = new Intent(view.getContext(), camerapic.class);

                        startActivityForResult(myIntent, 0);

                    }
                    if (position == 1) {
                        Intent myIntent = new Intent(view.getContext(), camerapic.class);
                        startActivityForResult(myIntent, 0);

                    }

                    if (position == 2) {
                        Intent myIntent = new Intent(view.getContext(), camerapic.class);
                        startActivityForResult(myIntent, 0);
                    }

                    if (position == 3) {
                        Intent myIntent = new Intent(view.getContext(), camerapic.class);
                        startActivityForResult(myIntent, 0);
                    }

                    if (position == 4) {
                        Intent myIntent = new Intent(view.getContext(), camerapic.class);
                        startActivityForResult(myIntent, 0);
                    }

                    if (position == 5) {
                        Intent myIntent = new Intent(view.getContext(), item1.class);
                        startActivityForResult(myIntent, 0);
                    }

                    if (position == 6) {
                        Intent myIntent = new Intent(view.getContext(), item1.class);
                        startActivityForResult(myIntent, 0);
                    }

                    if (position == 7) {
                        Intent myIntent = new Intent(view.getContext(), item1.class);
                        startActivityForResult(myIntent, 0);
                    }
                }
            });
        }
    }

Answer 1

您的活动的contentView和listview的项目视图是相同的??? R.layout.snag_item

        setContentView(R.layout.snag_item);

        final ArrayAdapter adapterSnag_Item = new ArrayAdapter<String>(this,
                R.layout.snag_item,R.id.textsnag, snaglistciv);

新列表视图项不可点击
