我有一个调用 onItemClick 并启动另一个活动的活动。这个活动有一个静态布局(用于测试目的),但我看到的只有黑色(我什至将文本颜色设置为白色以检查它)。
我的听众
list.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,long arg3) {
//create new intent
Intent item = new Intent(getApplicationContext(), Item.class);
// Close all views before launching logged
//item.putExtra("name", ((TextView)arg1).getText());
//item.putExtra("uid", user_id);
item.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(item);
// Close Login Screen
onPause();
}
});
我的活动在这里(没什么可做的,只是启动布局)
public class Item extends Activity{
protected SQLiteDatabase myDB=null;
protected String name;
protected int uid;
TextView yeart,year,itemname,comment,commentt,value,valuet,curr,currt;
protected void onStart(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.herp);
/*name=getIntent().getStringExtra("name");
uid=Integer.parseInt(getIntent().getStringExtra("uid"));
itemname=(TextView) findViewById(R.id.itemName);//itemname.setText(name);
year=(TextView) findViewById(R.id.itemYear);
yeart=(TextView) findViewById(R.id.year);
comment=(TextView) findViewById(R.id.itemComments);
commentt=(TextView) findViewById(R.id.comments);
curr=(TextView) findViewById(R.id.itemcurrent);
currt=(TextView) findViewById(R.id.current);
value=(TextView) findViewById(R.id.itemValue);
valuet=(TextView) findViewById(R.id.value);*/
Database openHelper = new Database(this);
myDB = openHelper.getReadableDatabase();
myDB=SQLiteDatabase.openDatabase("data/data/com.example.login2/databases/aeglea", null, SQLiteDatabase.OPEN_READONLY);
}}
最后是我的 XML 布局
