我的应用程序中有一个用于登录身份验证的警告对话框.在发送请求时,我想显示一个进度条,如果响应是成功则想要解雇.如果有人知道,请帮助我.我使用下面的代码：
final AlertDialog.Builder alert = new AlertDialog.Builder(this);
LinearLayout login = new LinearLayout(this);
TextView tvUserName = new TextView(this);
TextView tvPassword = new TextView(this);
TextView tvURL = new TextView(this);
final EditText etUserName = new EditText(this);
final EditText etPassword = new EditText(this);
final EditText etURL = new EditText(this);
login.setOrientation(1); // 1 is for vertical orientation
tvUserName.setText(getResources().getString(R.string.username));
tvPassword.setText(getResources().getString(R.string.password));
tvURL.setText("SiteURL");
login.addView(tvURL);
login.addView(etURL);
login.addView(tvUserName);
login.addView(etUserName);
login.addView(tvPassword);
etPassword.setInputType(InputType.TYPE_CLASS_TEXT
| InputType.TYPE_TEXT_VARIATION_PASSWORD);
login.addView(etPassword);
alert.setView(login);
alert.setTitle(getResources().getString(R.string.login));
alert.setCancelable(true);
alert.setPositiveButton(getResources().getString(R.string.login),new DialogInterface.OnClickListener() {
public void onClick(final DialogInterface dialog,int whichButton) {
strhwdXml = etURL.getText().toString();
strUserName = etUserName.getText().toString();
XmlUtil.username = strUserName;
strPassword = etPassword.getText().toString();
if ((strUserName.length() == 0)
&& (strPassword.length() == 0)
&& (strhwdXml.length() == 0)) {
Toast.makeText(
getBaseContext(),getResources().getString(
R.string.userPassword),Toast.LENGTH_SHORT).show();
onStart();
} else {
final SharedPreferences prefs = PreferenceManager
.getDefaultSharedPreferences(getApplicationContext());
SharedPreferences.Editor prefsEditor = prefs
.edit();
try {
StringBuffer inStreamBuf = new StringBuffer();
inStreamBuf = XmlUtil
.getLoginAuthResponse(strUserName,strPassword,strhwdXml);
strXmlResponse = inStreamBuf.toString();
Log.e("Response:",strXmlResponse);
String parsedXML = ParseResponse(strXmlResponse);
if (parsedXML
.equalsIgnoreCase(getResources()
.getString(R.string.success))) {
}
解决方法
使用它可能更容易
ProgressDialog dialog = ProgressDialog.show(MyActivity.this,"","Loading. Please wait...",true);
您可以阅读有关进度对话框here的更多信息
取消将是
dialog.dismiss();
This class was deprecated in API level 26. ProgressDialog is a modal dialog,which prevents the user from interacting with the app. Instead of using this class,you should use a progress indicator like ProgressBar,which can be embedded in your app’s UI. Alternatively,you can use a notification to inform the user of the task’s progress.For more details 07001
