[英]AlertDialog not showing inside OnClickListener
我想在alertDialog
顯示OnClickListener
。 但是當我在onclickListener
使用以下代碼時, alertDialog
沒有顯示出來。 任何幫助都會很棒。
final AlertDialog alertDialog = new AlertDialog.Builder(MyClass.this).create();
alertDialog.setTitle("Info:");
String alert1 = "First Name: " + Fname;
String alert2 = "Surname: " + Sname;
String alert3 = "Id: " + tId;
String alert4 = "Password: " + tPassword;
alertDialog.setMessage(alert1 +"\n"+ alert2 +"\n"+ alert3+"\n" + alert4);
alertDialog.setButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
startActivity(intent);
}
});
alertDialog.show();
}});
使用它會起作用
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setTitle("ALERTTILESTRING")
.setMessage("alertNameString")
.setCancelable(false)
.setPositiveButton("OK",new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
AlertDialog alert = builder.create();
alert.show();
在onclicklistner中添加以下代碼:
AlertDialog.Builder dialog1 = new AlertDialog.Builder(this);
dialog1.setTitle("Info:");
String alert1 = "First Name: " + Fname;
String alert2 = "Surname: " + Sname;
String alert3 = "Id: " + tId;
String alert4 = "Password: " + tPassword;
dialog1.setMessage(alert1 + "\n" + alert2 + "\n" + alert3 + "\n" + alert4);
dialog1.setButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
startActivity(intent);
}
});
dialog1.show();
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity(), R.style.AppCompatAlertDialogStyle);
builder.setTitle("");
builder.setMessage("");
builder.setPositiveButton("ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
//do stuff
}
});
builder.setNegativeButton("CLOSE", new DialogInterface.OnClickListener(){
public void onClick(DialogInterface dialog, int id){
//do stuff
}
});
builder.show();
