Did you inflate the correct layout file? activity_register is the name of the file you said, but your code uses
setContentView(R.layout.activity_login);.
Try replacing that with setContentView(R.layout.activity_register); if that's not the case.
This question already has answers here:
What is a stack trace, and how can I use it to debug my application errors?

Closed 4 years ago.
This is the code MainActivity.java file. I think there should be no mistake in this code. But it shows the message
Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'android.view.Window$Callback android.view.Window.getCallback()' on a null object reference.
I don't know why it is showing up there? Please help me to figure out.

Here is the image of it should look like it is the screenshot the preview
All these findViewById must be included in your onCreate() method. You can keep the declarations out of onCreate(). Your views do not exist before setContentView(R.layout.activity_main);
I mean before onCreate() you can have Button b1;
and after setContentView(R.layout.activity_main); in onCreate() you must have b1=(Button)findViewById(R.id.b_i1);
for every view.
I have made the corrections in your and now the app is not crashing. Try using the below code snippet
MainActivity
public class MainActivity extends AppCompatActivity {

Hope this helps.
My app contains a few textViews which are supposed to be scrolling horizontally. This works when my layout is first loaded but after clicking on a button to load another layout and then re-click on that button to load back the first layout those textViews start scrolling after a "big" delay(like 20 secs+). I'm trying to figure out the source of this problem with the Layout Inspector, Hierarchy Viewer etc. but no luck.
UPDATE: I noticed something strange today.When i go from the 1st layout to the 2nd one and vice versa, although the TextViews stop scrolling, if i close and re-open the phone's screen, the scrolling works like a charm. This seems totally strange to me, do you know what's causing this and why?

I'd suggest using a RecyclerView with a custom Adapter, RecyclerView can be used vertically or horizontally.
I'm having a strange trouble and didn't find any solutions on the web.
I'm adding a TextView dynamically into a RelativeLayout, with custom fonts, and sometimes the text appears underlined.
public void bouton_valide_ajout_texte(View v)
{
new_text_view.setText(((TextView) dialog.findViewById(R.id.edit_ajoute_texte)).getText());
RelativeLayout rl_newtext_1 = (RelativeLayout)findViewById(R.id.rl_newtext_1);
rl_newtext_1.addView(new_text_view);*/
TextView text_view = new TextView(this);
text_view.setText(((TextView) dialog_ajoute_texte.findViewById(R.id.edit_ajoute_texte)).getText());
ListView liste_view_police = (ListView) dialog_ajoute_texte.findViewById(R.id.list_view_dialog_polices);
text_view.setTextSize(TypedValue.COMPLEX_UNIT_SP,12);
text_view.setTypeface(listePolices.get_typeface(position_item_police));
text_view.setTextColor(Color.argb(255, 0, 0, 0));
text_view.clearComposingText();
container_calques.addView(text_view);
Object[] tab_calque = new Object[5];
tab_calque[0]="texte";
tab_calque[1]=text_view;
tab_calque[2]=12;
tab_calque[3]=0;
liste_calques.add(tab_calque);
calque_selectionne=liste_calques.size()-1;
text_view.setOnTouchListener(new TouchListener_calque(liste_calques.size()-1));
dialog_ajoute_texte.hide();
}

Solved
I replaced
text_view.setText(((TextView);
dialog_ajoute_texte.findViewById(R.id.edit_ajoute_texte)).getText());
By
text_view.setText(((EditText);
dialog_ajoute_texte.findViewById(R.id.edit_ajoute_texte)).getText().toString());
The possible underline could by the ListView as it puts a divider between its items. Look at this answer to get rid of the divider
Please make sure you don't have any inputType to your textview as follows
android:inputType="something"
Strangely, my listView's onClick no longer works after I added two Buttons: Submit and Show Result.
Here is the list view xml.

Here is the click snippet of the list view:
listview.setOnItemClickListener( new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View view,
int position, long id) {
long audit_id;
try{
audit_id = (new CustomListAdapter(HomeList.this, c).getAuditID(position));
changeTileStatus(audit_id,"opened");
System.out.println("listClicked");
sendAuditAndIntent(audit_id);
}catch(Exception e)
{
System.out.println("ERROR # HOMELIST list onClick: "+e);
}
}
private void sendAuditAndIntent(long audit_id) { //sends audit id and api key
Intent intent = new Intent(HomeList.this,ChapterActivity.class );
Bundle extras= new Bundle();
extras.putString("audit_id",String.valueOf(audit_id));
extras.putString("api_key", api_key);
intent.putExtras(extras);
startActivity(intent);
}
private void changeTileStatus(long audit_id, String value) {
AuditTableManager tile= new AuditTableManager(HomeList.this);
tile.open();
tile.updateEntry(audit_id, value);
tile.close();
}
});
OnItemClickListener is not called if cells contain clickable Views. It is an Android feature. You can handle clicks by OnClickListener then - set it to your two buttons (not the listView itself).
In your adapter:
public View onCreateView(..., final int position){
...
convertView.findViewById(R.id.button1).setOnClickListener(new OnClickListener(){
public void onClick(View view){
itemClickedAction1(position);
}
});
convertView.findViewById(R.id.button2).setOnClickListener(new OnClickListener(){
public void onClick(View view){
itemClickedAction2(position);
}
});
...
}
Try android:Focusable="false" and also android:clickable="false" in the custom row TextView
