我有一个活动，其中打开一个对话框，显示社交网络图标列表。单击该图标，它将在同一个应用程序而不是浏览器中打开该站点，但是当我们在输入用户名和密码后点击登录时出现问题，它显示以下异常：

这是我的代码：
public class ShareActivity extends Activity implements OnItemClickListener {
//public static ShareActivity context;
WebView wv;
boolean land_scape=false;
ProgressDialog pdlg;
String links[]= new String[]{"Facebook","Twitter","Google Plus","Pintrest"};
ListView lv1;
Dialog dialog ;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
int currentOrientation = getResources().getConfiguration().orientation;
if (currentOrientation == Configuration.ORIENTATION_LANDSCAPE) {
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR_LANDSCAPE);
land_scape=true;
}
else {
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR_PORTRAIT);
land_scape=false;
}
setContentView(R.layout.share_layout);
//context=this;
wv=(WebView)findViewById(R.id.webView1);
wv.getSettings().setJavaScriptEnabled(true);
dialog = new Dialog(ShareActivity.this.getParent());
dialog.setTitle("Please select");
dialog.setCanceledOnTouchOutside(false);
dialog.setContentView(R.layout.share_list);
lv1=(ListView)dialog.findViewById(R.id.listShare);
lv1.setAdapter(new CustomShareAdapter(this,links));
lv1.setOnItemClickListener(this);
dialog.show();
}
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
switch(arg2)
{
case 0:
wv.loadUrl("http://www.facebook.com");
break;
case 1:
wv.loadUrl("https://mobile.twitter.com/login");
break;
case 2:
wv.loadUrl("http://www.plus.google.com");
break;
case 3:
wv.loadUrl("http://www.pinterest.com");
break;
}
wv.setWebViewClient(new WebViewClient());
dialog.dismiss();
}
@Override
public void onResume()
{
//Determine screen size
if ((getResources().getConfiguration().screenLayout & Configuration.SCREENLAYOUT_SIZE_MASK) == Configuration.SCREENLAYOUT_SIZE_LARGE) {
//Toast.makeText(this, "Large screen set to landscape",Toast.LENGTH_LONG).show();
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR_LANDSCAPE);
land_scape=true;
}
else if ((getResources().getConfiguration().screenLayout & Configuration.SCREENLAYOUT_SIZE_MASK) == Configuration.SCREENLAYOUT_SIZE_NORMAL) {
//Toast.makeText(this, "Normal sized screen set to portrait" , Toast.LENGTH_LONG).show();
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR_PORTRAIT);
land_scape=false;
}
else if ((getResources().getConfiguration().screenLayout & Configuration.SCREENLAYOUT_SIZE_MASK) == Configuration.SCREENLAYOUT_SIZE_SMALL) {

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR_PORTRAIT);
land_scape=false;
}
else {
//Toast.makeText(this, "Screen size is neither large, normal or small" , Toast.LENGTH_LONG).show();
land_scape=false;
}
super.onResume();
}
@Override
public void onBackPressed() {
Intent backIntent = new Intent(this, MainActivity.class);
startActivity(backIntent);
super.onBackPressed();
}
}
第二个问题：它还显示我没有设置的空屏幕。我在这方面进行了很多搜索。请帮我。
