public class PureJavaListActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ListView mListView = new ListView(this);
mListView.setLayoutParams(new LayoutParams(-1, -1));
mListView.setAdapter(new BaseAdapter() {
@Override
public View getView(final int position, View convertView,
ViewGroup parent) {
if (convertView == null) {
TextView tv = new TextView(PureJavaListActivity.this);
tv.setTextSize(TypedValue.COMPLEX_UNIT_SP, 20);
tv.setPadding(20, 20, 20, 20);
tv.setTextColor(Color.BLACK);
convertView = tv;
}
TextView tv = (TextView) convertView;
tv.setText("TextView:" + position);
tv.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
startActivity(new Intent(PureJavaListActivity.this,
PureJavaDetailsActivity.class).putExtra(
"content", "content:" + position));
}
});
return tv;
}
@Override
public long getItemId(int position) {
return 0;
}
@Override
public Object getItem(int position) {
return null;
}
@Override
public int getCount() {
return 50;
}
});
}
}
这是列表，下面的是详情
public class PureJavaDetailsActivity extends Activity {
/* (non-Javadoc)
* @see android.app.Activity#onCreate(android.os.Bundle)
*/
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextView mTextView=new TextView(this);
mTextView.setLayoutParams(new LayoutParams(-1, -1));
mTextView.setTextSize(20);
mTextView.setText(getIntent().getStringExtra("content"));
}
}
这只是一些非常简单的DEMO，仅供参考，但是要提醒一句Activity想要运行的话，必须要在AndroidManifest.xml文件中配置
