android – 在警告对话框中显示进度条
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
android – 如何在对话框上添加进度条
每当我想在我的应用程序中显示进度条时,我调用此方法,此方法将ProgressBar添加到我的布局中.
问题：我想在Dialog上显示此进度条,但Dialog始终显示在上面.这种情况可以做些什么？
public static void showProgressBar(@NonNull final Activity activity) {
try {
if (activity == null) {
LogManager.printstacktrace(new NullActivityException());
return;
}
View view = activity.findViewById(android.R.id.content);
if (view == null) {
LogManager.printstacktrace(new NullPointerException("content view is null"));
return;
}
View rootView = activity.findViewById(android.R.id.content).getRootView();
if (rootView == null || !(rootView instanceof ViewGroup)) {
LogManager.printstacktrace(new NullPointerException("rootView is null or not an instance of ViewGroup"));
return;
}
final ViewGroup layout = (ViewGroup) rootView;
final ProgressBar progressBar = new ProgressBar(activity);
progressBar.setIndeterminate(true);
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
Drawable wrapDrawable = DrawableCompat.wrap(progressBar.getIndeterminateDrawable());
DrawableCompat.setTint(wrapDrawable,ContextCompat.getColor(activity,R.color.colorAccent));
progressBar.setIndeterminateDrawable(DrawableCompat.unwrap(wrapDrawable));
}
RelativeLayout.LayoutParams params = new
RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT,RelativeLayout.LayoutParams.MATCH_PARENT);
final RelativeLayout rl = new RelativeLayout(activity);
rl.setBackgroundColor(ActivityCompat.getColor(activity,R.color.tc_hint_grey_alpha));
rl.setClickable(true);
rl.setTag("#$UniqueProgressBar");
ViewGroup.LayoutParams params2 = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,120);
rl.setGravity(Gravity.CENTER);
rl.addView(progressBar,params2);
LogManager.i("ProgressBar","ProgressUtils.showProgressBar->called");
layout.addView(rl,params);
mRunnable = new Runnable() {
@Override
public void run() {
LogManager.i("ProgressBar","ProgressUtils.showProgressBar->120 secs timeout");
hideProgressBar(activity);
}
};
mHandler = new Handler();
mHandler.postDelayed(mRunnable,120000);
LogManager.i("ProgressBar","Added");
} catch (Exception e) {
LogManager.printstacktrace(e);
}
}
解决方法
尝试这样的东西,它应该全局工作：
public static void showProgressBar(@NonNull final Activity activity) {
try {
if (activity == null) {
LogManager.printstacktrace(new NullActivityException());
return;
}
final WindowManager wm = (WindowManager) activity.getApplicationContext().getSystemService(Activity.WINDOW_SERVICE);
final ProgressBar progressBar = new ProgressBar(activity);
progressBar.setIndeterminate(true);
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
Drawable wrapDrawable = DrawableCompat.wrap(progressBar.getIndeterminateDrawable());
DrawableCompat.setTint(wrapDrawable,R.color.colorAccent));
progressBar.setIndeterminateDrawable(DrawableCompat.unwrap(wrapDrawable));
}
WindowManager.LayoutParams windowLayoutParams = new WindowManager.LayoutParams();
windowLayoutParams.gravity = Gravity.CENTER;
windowLayoutParams.type = WindowManager.LayoutParams.TYPE_APPLICATION_PANEL;
windowLayoutParams.token = activity.getwindow().getDecorView().getwindowToken();
windowLayoutParams.flags = WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE;
windowLayoutParams.height = LayoutParams.MATCH_PARENT;
windowLayoutParams.width = LayoutParams.MATCH_PARENT;
wm.addView(progressBar,windowLayoutParams);
LogManager.i("ProgressBar","Added");
} catch (Exception e) {
LogManager.printstacktrace(e);
}
}
android – 用于打开另一个对话框的对话框
如果一个人在用对话框回答选择问题后选择一个特定的答案,我想跟进一个对话框.
在此示例中,如果此人选择“Choice1”,则应打开另一个对话框以询问更多问题.
我在下面有以下部分代码：
private void openDialog1()
{
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setTitle("Select Choice");
builder.setSingleChoiceItems(ChoiceLists.listofchoices,-1,new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialog,int item)
{
ccRewardDialog.dismiss();
String finalString = "";
if((ChoiceLists.listofchoices[item].equals("Choice1")) || (ChoiceLists.listofchoices[item].equals("Choice2")))
{
openDialog2();
}
TextView tv1 = (TextView) getActivity().findViewById(R.id.tv1);
finalString = ChoiceLists.strRewards[item];
if(!RESULT.equals("")) //RESULT being a global value
{
finalString = finalString + "-" + RESULT;
RESULT = "";
}
tv1.setText(tv1.getText() + finalString + "\n");
}
});
dialog1 = builder.create();
dialog1.show();
}
private void openDialog2()
{
LayoutInflater li = LayoutInflater.from(getActivity());
View promptView = li.inflate(R.layout.reward_detail_prompt,null);
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setView(promptView);
final EditText userInput = (EditText) promptView.findViewById(R.id.etRewardDetail);
builder.setCancelable(false);
builder.setPositiveButton("OK",new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialog,int id)
{
RESULT = userInput.getText().toString();
}
});
builder.setNegativeButton("Cancel",int which)
{
RESULT = ""; //RESULT being a global value
}
});
}
如果我不这样做的话.你会怎么做呢？提前致谢.我正在继续学习更多知识,感谢所有的帮助
解决方法
刚刚完成你的第二种方法
private void openDialog2()
{
...
builder.create().show();
}
