        ly.addView(tv);
        lLayout.addView(ly);

                                @Override
                                public void onClick(View v) {

                                Intent in = new Intent(MainActivity.this, SubCate.class);

                               startActivity(in); 

                                }

回答1:

if you want to use intents:

while going to the ListActivity pass data by..

intent.putExtra("Title", yourstring);
intent.putExtra("Content", yourstring);
startActivity(intent);

and to recover it in second activity use:

title= getIntent().getExtras().getString("Title");

...and so on..

回答2:

//to pass :
 Intent in = new Intent(MainActivity.this, SubCate.class);
in.putExtra("name", "Artical Name");  
 startActivity(in);


// to retrieve object in second Activity
getIntent().getSerializableExtra("name");

回答3:

 public void onClick(View view)
 {
    public void run()
    {
            Intent i=new Intent(activity1.this,activity2.class);
            i.putExtra("somename", variable1);
            i.putExtra("somename1", variable2);         

    }
 }

In the second activity

     Bundle extras = getIntent().getExtras();
    if (extras != null) {
        one= extras.getDouble("somename");
        two = extras.getDouble("somename2");

    }
