Question

我想启动保留在src下的每个意图。它们被命名为One.java，Two.java等等。

这是我的java代码，但在点击GridView项目后，它会打开相同的Intent窗口，而不是One.java或Two.java活动。

MyActivity.java：

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.GridView;
public class MyActivity extends Activity {  

static final String[] numbers = new String[] { "One", "Two", "Three", "Four", "Five", "Six",  "Seven"  };

@Override
    public void onCreate(Bundle savedInstanceState) {      
        super.onCreate(savedInstanceState);
        setContentView(R.layout.myactivity);

        GridView gv = (GridView) findViewById(R.id.gridView1);

        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, numbers);

        gv.setAdapter(adapter);
        gv.setOnItemClickListener(new OnItemClickListener() {
        public void onItemClick(AdapterView<?> parent, View v,int position, long id) {
                Intent i = new Intent(getApplicationContext(), MyActivity.class);
                i.putExtra("id", position);
                startActivity(i);
            }
        });
    }
}

这会有所帮助：

Android Gridview - Need to open different intents

Answer 1

以下是如何为网格视图中的每个位置启动意图的示例：

gv.setOnItemClickListener(new OnItemClickListener() {


            public void onItemClick(AdapterView<?> parent, View v,int position, long id) {

                switch (position) {
                case 0:

                    Intent i = new Intent(getApplicationContext(), MyActivity.class);
                    i.putExtra("id", position);
                    startActivity(i);
                    break;

                case 1:
                    //Use some different intent here
                    Intent j = new Intent(getApplicationContext(), MyActivity.class);
                    j.putExtra("id", position);
                    startActivity(j);
                    break;
                case 2:
                    //Use some different intent here
                    Intent k = new Intent(getApplicationContext(), MyActivity.class);
                    k.putExtra("id", position);
                    startActivity(k);
                    break;
                case 3:
                    //Use some different intent here
                    Intent l = new Intent(getApplicationContext(), MyActivity.class);
                    l.putExtra("id", position);
                    startActivity(l);
                    break;

                default:
                    break;
                }



            }
            });

我希望这就是你要找的东西。

我怎么能 - 通过GridView项目开始意图点击＆＃34; （不是图像）
