我有一行数据将在多个活动中使用的数据库。我需要能够保持行ID提供一切活动都让我可以阅读和我的数据库适配器写在不同的activites数据。我已经成功地使用putExtra（Overthelimit.java）通过一个意图行ID传递到下一个活动。那么mRowId变量给出的行ID使用getExtra（Profile.java）。这个问题我现在已经是可用于其他活动mRowId即MyUsual和DrinksList，所以我可以，我去更新数据。
您可以看到我已经试过putExtras，putSerializable但不能让它开始工作。我想我错过了一些了解。
因此，对于下面的活动我的个人资料菜单选项，我可以把光标行id的值，以文件类：

然后我需要让这个mRowId提供给所谓的DrinkList从MyUsual另一项活动。所以我下面有一个drink1按钮onClickListener MyUsual尝试发送行ID来DrinksList：

很抱歉的长期职位，但我需要做的是使这个值mRowId适用于一切活动都让我可以在任何时候读/写数据。数据还需要存在，如果应用程序被暂停或者说来电interupted，所以我用的onSaveInstanceState。
好的，谢谢。所以回复伟大的答案，我已经做到了这一点，但它崩溃试图获取数据。我有这个作为我的应用程序类：
公共类OverthelimitApplication扩展应用{
私人龙ROWID;
众长getRowId（）{
返回ROWID;
}
公共无效setRowId（Long值）{
ROWID =价值;
}
}
然后设置值是：
OverthelimitApplication APP1 =（OverthelimitApplication）getApplicationContext（）;
app1.setRowId（（长）cursor.getColumnIndexOrThrow（OverLimitDbAdapter.KEY_ROWID））;
然后尝试获得价值这一点，它崩溃了：
mRowId =（（OverthelimitApplication）getApplicationContext（））getRowId（）。
我有固定它！使用此设置和获取：
app1.setRowId(Long.parseLong(cursor.getString(cursor.getColumnIndexOrThrow(OverLimitDbAdapter.KEY_ROWID)))); mRowId =（长）（（OverthelimitApplication）getApplicationContext（））getRowId（）。
我仍然有指定长设置和获取时。感谢您的输入。
解决方案另一种方法是创建一个适用于所有的活动应用程序类。 要做到这一点，你必须对你的清单扩展以
＆lt;应用
..
机器人：名称=。MyApplication的＆GT;
和创建一个新的类
公共类MyApplication的扩展应用{
公众诠释ROWID = 0;
}
在活动里面，你可以通过
访问ROWID INT mRowId =（（所有MyApplication）getApplicationContext（））ROWID。
I have a database with one row of data that will be used across a number of activities. I need to be able to keep the row id available in all activites so I can read and write data across different activites with my DB adapter. I have successfully used putExtra (Overthelimit.java) via an intent to pass a row id to the next activity. mRowId variable is then given the row id using getExtra (Profile.java). The problem I now have is making mRowId available to other activities i.e. MyUsual and DrinksList so I can update data as I go.
You can see I have tried putExtras, putSerializable but can't get it to work. I think I am missing some understanding.
So for my profile menu option in the activity below I can send the value of the cursor row id to Profile class:
public class Overthelimit extends ListActivity {
private OverLimitDbAdapter dbHelper;
private Cursor cursor;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
this.getListView();
dbHelper = new OverLimitDbAdapter(this);
dbHelper.open();
fillData();
registerForContextMenu(getListView());
}
@Override
protected void onActivityResult(int requestCode, int resultCode,
Intent intent) {
super.onActivityResult(requestCode, resultCode, intent);
fillData();
}
private void fillData() {
cursor = dbHelper.fetchAllUserDrinks();
startManagingCursor(cursor);
//cursor.getCount();
String[] from = new String[] { OverLimitDbAdapter.KEY_USERNAME };
int[] to = new int[] { R.id.label };
// Now create an array adapter and set it to display using our row
SimpleCursorAdapter notes = new SimpleCursorAdapter(this,
R.layout.user_row, cursor, from, to);
setListAdapter(notes);
}
@Override
protected void onDestroy() {
super.onDestroy();
if (dbHelper != null) {
dbHelper.close();
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main_menu, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle item selection
switch (item.getItemId()) {
case R.id.profile:
Intent myIntent1 = new Intent(this, Profile.class);
if(cursor.getCount() != 0) {
//Toast.makeText(getApplicationContext(), "no profile",Toast.LENGTH_SHORT).show();
myIntent1.putExtra(OverLimitDbAdapter.KEY_ROWID, cursor.getString(cursor.getColumnIndexOrThrow(OverLimitDbAdapter.KEY_ROWID)));
}
startActivityForResult(myIntent1, 0);
return true;
case R.id.myusual:
Intent myIntent2 = new Intent(this, MyUsual.class);
startActivityForResult(myIntent2, 0);
return true;
case R.id.trackme:
Intent myIntent3 = new Intent(this, TrackMe.class);
startActivityForResult(myIntent3, 0);
return true;
case R.id.moreinfo:
Intent myIntent4 = new Intent(this, MoreInfo.class);
startActivityForResult(myIntent4, 0);
return true;
}
return super.onOptionsItemSelected(item);
}
}
Then make it available as mRowId in my Profile activity below:
mRowId = (bundle == null) ? null :
(Long) bundle.getSerializable(OverLimitDbAdapter.KEY_ROWID);
if (mRowId == null) {
Bundle extras = getIntent().getExtras();
mRowId = extras != null ? Long.parseLong(extras.getString(OverLimitDbAdapter.KEY_ROWID))
: null;
}
I then need to make this mRowId available to another activity called DrinkList from MyUsual. so I have MyUsual below with a drink1 button onClickListener to try and send the row id to DrinksList:
public class MyUsual extends Activity {
private Long mRowId;
private OverLimitDbAdapter mDbHelper;
private Cursor cursor;
private TextView mDrink1Label;
private TextView mDrink1Units;
/** Called when the activity is first created. */
@Override
public void onCreate(final Bundle bundle) {
super.onCreate(bundle);
mDbHelper = new OverLimitDbAdapter(this);
mDbHelper.open();
setContentView(R.layout.my_usual);
mDrink1Label = (TextView) findViewById(R.id.drink1Label);
mDrink1Units = (TextView) findViewById(R.id.drink1Units);
Button drink1 = (Button) findViewById(R.id.drink1Button);
// get intent data i.e. which drink button pressed and mRowId
mRowId = (bundle == null) ? null :
(Long) bundle.getSerializable(OverLimitDbAdapter.KEY_ROWID);
if (mRowId == null) {
Bundle extras = getIntent().getExtras();
mRowId = extras != null ? Long.parseLong(extras.getString(OverLimitDbAdapter.KEY_ROWID))
: null;
}
//populateFields();
drink1.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
setResult(RESULT_OK);
//finish();
Intent myIntent1 = new Intent(view.getContext(), DrinksList.class);
myIntent1.putExtra("drinkButton", "drink1");
if(cursor.getCount() != 0) {
myIntent1.putExtra(OverLimitDbAdapter.KEY_ROWID, cursor.getString(cursor.getColumnIndexOrThrow(OverLimitDbAdapter.KEY_ROWID)));
}
startActivityForResult(myIntent1, 0);
}
});
}
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
//saveState();
outState.putSerializable(OverLimitDbAdapter.KEY_ROWID, mRowId);
}
}
From DrinksList I select a drink and I need to use the mRowId write the data to the database via the onListItemclick:
public class DrinksList extends ListActivity {
private ProgressDialog m_ProgressDialog = null;
private ArrayList<CreateDrinkOption> m_drinks = null;
private DrinkAdapter m_adapter;

Sorry for the long post, but all I need to do is make this value for mRowId available to all activites so I can read/write data at any point. The data also needs to be there if the app is paused or interupted by say an incoming call, so I use onSaveInstanceState.
ok, thanks. So reply to great answers and I have done this, but it crashes trying to get the data. I have this as my Application class:
public class OverthelimitApplication extends Application {
private Long rowId;
public Long getRowId() {
return rowId;
}
public void setRowId(Long value) {
rowId = value;
}
}
then set value with this:
OverthelimitApplication app1 = (OverthelimitApplication)getApplicationContext();
app1.setRowId((long) cursor.getColumnIndexOrThrow(OverLimitDbAdapter.KEY_ROWID));
then try to get value with this and it crashes:
mRowId = ((OverthelimitApplication) getApplicationContext()).getRowId();
I have fixed it! using this the set and get:
app1.setRowId(Long.parseLong(cursor.getString(cursor.getColumnIndexOrThrow(OverLimitDbAdapter.KEY_ROWID))));
mRowId = (long)((OverthelimitApplication)getApplicationContext()).getRowId();
I still had to specify long when setting and getting. Thanks for all your input.
解决方案Another way is to create a application class which is available for all activities. To do that, you have to extend you Manifest with
<application
..
android:name=".MyApplication" >
and create a new Class
public class MyApplication extends Application {
public int rowId = 0;
}
inside the activities, you can access the rowId by
int mRowId = ((MyApplication) getApplicationContext()).rowId;
