概述我正在使用以下方式开始新的活动Intentedit=newIntent(getParent(),WebViewLink.class);TabGroupActivityparentActivity=(TabGroupActivity)getParent();edit.putExtra(POSITION,FAQ);parentActivity.startChildActivity("WebViewLink",edit);我收到这样的错误

我正在使用以下方式开始新的活动

Intent edit = new Intent(getParent(), WebVIEwlink.class);TabGroupActivity parentActivity = (TabGroupActivity) getParent();edit.putExtra(position, FAQ);parentActivity.startChildActivity("WebVIEwlink", edit);

我收到这样的错误

但是当我使用这种方式来调用new Activity时没有问题

Intent edit = new Intent(getParent(), WebVIEwlink.class);edit.putExtra(position, FAQ);More.this.startActivity(edit);

你可以在这里看到我的WebVIEwlink.java类

public class WebVIEwlink extends Activity {public static String position = "position";int position = 0;private button back;private TextVIEw ttl;ProgressDialog myProgressDialog = null;private WebVIEw webVIEw;@OverrIDepublic voID onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    requestwindowFeature(Window.FEATURE_NO_Title);    getwindow().setFlags(WindowManager.LayoutParams.FLAG_FulLSCREEN,            WindowManager.LayoutParams.FLAG_FulLSCREEN);    setContentVIEw(R.layout.webvIEw);    webVIEw = (WebVIEw) findVIEwByID(R.ID.webvIEw);    back = (button) findVIEwByID(R.ID.backtomore);    ttl = (TextVIEw) findVIEwByID(R.ID.my_Title);    webVIEw.getSettings().setJavaScriptEnabled(true);    if (getIntent().getExtras() != null) {        if (getIntent().getExtras().containsKey(position)) {            position = getIntent().getExtras().getInt(position);        }    }    switch (position) {    case More.FAQ:        ttl.setText("FAQ");        setWeblink();        webVIEw.loadUrl("file:///androID_asset/faq4.htm");        break;    case More.ABOUT_US:        ttl.setText("About Us");        setWeblink();        webVIEw.loadUrl("file:///androID_asset/Advice/About Us.HTML");        break;    case More.disCLaimMER:        ttl.setText("disclaimer");        setWeblink();        webVIEw.loadUrl("file:///androID_asset/Advice/disclaimer.HTML");        break;    }    back.setonClickListener(new OnClickListener() {        public voID onClick(VIEw v) {            finish();        }    });}private voID setWeblink() {    webVIEw.setWebVIEwClIEnt(new WebVIEwClIEnt() {        public boolean shouldOverrIDeUrlLoading(WebVIEw vIEw, String url) {            vIEw.loadUrl(url);            return true;        }        public voID onl oadResource(WebVIEw vIEw, String url) {            if (myProgressDialog == null) {                myProgressDialog = new ProgressDialog(WebVIEwlink.this);                myProgressDialog.setMessage("Loading.... Please Wait");                myProgressDialog.show();            }        }        public voID onPageFinished(WebVIEw vIEw, String url) {            if (myProgressDialog.isShowing()) {                myProgressDialog.dismiss();            }        }    });}

}

解决方法:

问题出在这行代码中：

myProgressDialog = new ProgressDialog(WebVIEwlink.this);

当你是TabGroupActivity然后子Activity时,需要父母的Context来添加新的windows,Dialogs.试试这种方式：

myProgressDialog = new ProgressDialog(WebVIEwlink.this.getParent());

并为所有对话框执行相同 *** 作.
