如何等待另一個活動導致android。 我寫了下面的代碼，但活動完成後，它總是去onCreate（）方法。Android等待另一個活動結果 - 它沒有工作
我有標籤activity.From一個選項卡活動，我叫另一項活動，即彈出窗口......完成後彈出窗口應該回到以前的活動
@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
super.onListItemClick(l, v, position, id);
Object o = this.getListAdapter().getItem(position);
keyword = o.toString();
positions = position;
if(position != 0){
Bundle bundle = new Bundle();
Intent showContent = new Intent(getApplicationContext(),SalesRouteDevitionActivity.class);
int postion = position;
String aString = Integer.toString(postion);
bundle.putString("positon", aString);
showContent.putExtras(bundle);
startActivityForResult(showContent,0);
}else{
Intent intent = new Intent(SalesRouteActivity.this, ListRetailerActivity.class);
Bundle bundle = new Bundle();
bundle.putString("RouteName", keyword);
intent.putExtras(bundle);
View view = SalesActivityGroup.group.getLocalActivityManager().startActivity("", intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)).getDecorView();
SalesActivityGroup.group.replaceView(view);
}
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
Log.w("onActivityResult" ," --requestCode ---" + requestCode + " -- resultCode -- " + resultCode + " -- data --" + data);
if(resultCode==0){
Toast.makeText(this, "Reason has been successfully.", Toast.LENGTH_LONG).show();
if(resultCode==RESULT_OK)
Toast.makeText(this, "Reason has been successfully.", Toast.LENGTH_LONG).show();
else
Toast.makeText(this, "Fail", Toast.LENGTH_LONG).show();
}
}
和SalesRouteDevitionActivity.class
public class SalesRouteDevitionActivity extends Activity {
private String array_spinner[];
String param1 = "";
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.route_diviation_popup);
array_spinner=new String[2];
array_spinner[0]="Rain";
array_spinner[1]="Floods";
Spinner s = (Spinner) findViewById(R.id.spinner1);
ArrayAdapter adapter = new ArrayAdapter(this, android.R.layout.simple_spinner_dropdown_item, array_spinner);
s.setAdapter(adapter);
Button button = (Button) findViewById(R.id.submit);
button.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
Intent mIntent = new Intent();
setResult(RESULT_OK);
finish();
}
});
}
}
這是我的標籤Activity.I正在使用的ActivityGroup
public class MainActivity extends TabActivity {
int selectedTab;
TabHost tabHost ;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tabview);
TabHost t = getTabHost();
tabHost = (TabHost)findViewById(android.R.id.tabhost);
TabSpec firstTabSpec = tabHost.newTabSpec("tid1");
TabSpec secondTabSpec = tabHost.newTabSpec("tid1");
TabSpec thirdTabSpec = tabHost.newTabSpec("tid1");
/** TabSpec setIndicator() is used to set name for the tab. */
/** TabSpec setContent() is used to set content for a particular tab. */
firstTabSpec.setIndicator("Sales").setContent(new Intent(this,SalesActivityGroup.class));
secondTabSpec.setIndicator("Admin").setContent(new Intent(this,SettingActivityGroup.class));
thirdTabSpec.setIndicator("Setting").setContent(new Intent(this,SettingActivityGroup.class));
tabHost.addTab(firstTabSpec);
tabHost.addTab(secondTabSpec);
tabHost.addTab(thirdTabSpec);
tabHost.setCurrentTab(0);
tabHost.setMinimumHeight(25);
}
public void onTabChanged(String arg0) {
selectedTab = tabHost.getCurrentTab();
}
這是SalesActivityGroup.java
public class SalesActivityGroup extends ActivityGroup {
public static SalesActivityGroup group;
private ArrayList<View> history;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.history = new ArrayList<View>();
group = this;
View view = getLocalActivityManager().startActivity("Sales",
new Intent(this, SalesRouteActivity.class).addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP))
.getDecorView();
replaceView(view);
}
public void replaceView(View v) {
history.add(v);
setContentView(v);
}
public void back() {
if (history.size() > 0) {
history.remove(history.size() - 1);
if (history.size() > 0) {
setContentView(history.get(history.size() - 1));
} else {
finish();
}
} else {
finish();
}
}
@Override
public void onBackPressed() {
SalesActivityGroup.group.back();
return;
}
}
我知道這是我們應該做的方式，但我真的不知道爲什麼它不工作我而言....
我沒去onActivityResult（）方法&它沒有打印Log也
請幫助我..
在此先感謝
