Android XML file preventing Activity to open

Android XML file preventing Activity to open - java

I am learning android and so I wrote the following code for learning ScrollView and creating multiple linearlayouts inside a linearlayout. I have created a menu to launch different activities, but the problem is when I click the class associated with this xml file, the new class (activity) doesn't show up on the screen. What can be the problem and how can I fix it? here is the code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:weightSum="100"
android:padding="25dp" >
<ScrollView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="30"
>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
>
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Name" />

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Age" />
<EditText
android:id="#+id/editText2"

<EditText

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ems="10" />
</LinearLayout>
</ScrollView>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:layout_weight="40">
<Button
android:id="#+id/button1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:paddingTop="20dp"

</LinearLayout>
<LinearLayout

android:orientation="vertical">
<AnalogClock
android:id="#+id/analogClock1"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</LinearLayout>
The class Email code:
package com.umer.practice2;
import android.app.Activity;
import android.os.Bundle;
import android.widget.AnalogClock;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
public class Email extends Activity {
TextView t1,t2,t3,t4,t5,t6;
EditText e1,e2,e3,e4,e5,e6;
Button butn;
AnalogClock clock;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.email);
initializeviews();
}
private void initializeviews() {
// TODO Auto-generated method stub
t1= (TextView) findViewById(R.id.textView1);
t2= (TextView) findViewById(R.id.textView2);
t3= (TextView) findViewById(R.id.textView3);
t4= (TextView) findViewById(R.id.textView4);
t5= (TextView) findViewById(R.id.textView5);
t6= (TextView) findViewById(R.id.textView6);
e1= (EditText) findViewById(R.id.editText1);
e2= (EditText) findViewById(R.id.editText2);
e3= (EditText) findViewById(R.id.editText3);
e4= (EditText) findViewById(R.id.editText4);
e5= (EditText) findViewById(R.id.editText5);
e6= (EditText) findViewById(R.id.editText6);
butn=(Button) findViewById(R.id.button1);
clock= (AnalogClock) findViewById(R.id.analogClock1);
}
}

Did you added the activity in AndroidManifest.xml? Every activity need to be added into the manifest file.
for example:
<activity android:name=".HelloGoogleMaps" android:label="#string/app_name"/>

The issue is when I don't put any value into the firstEditText or secondEditText or both of them and click on any button then the app crashes and a pop up shows "myapp keeps stopping".
I cannot get the text and am unsure of why the app keeps crashing.

you have defined your Edit texts in the first activity with id's named
edtPhone
edtMessage
but there was no edtPhone or edtMessage in your xml.
this issue also repeats in your second activity
you have defined txtPhone and txtMessage
but again there are no such ids in your second activity XML.
keep in mind that these might not be the whole problem as you didn't post any log for the errors. but if there were anything else, ask and we'll help you

Widgets aren't being casted. how do I fix it?

"Caused by: java.lang.ClassCastException: android.support.v7.widget.AppCompatTextView cannot be cast to com.rey.material.widget.TextView"

Check your imports in SignIn.java. You are probably importing com.rey.material.widget.TextView instead of android.widget.TextView.
If you want to use the com.rey TextView instead of the normal one you have to write
<com.rey.material.widget.TextView
android:id="#+id/txtForgotPwd"
android:textColor="#android:color/white"
...
in your xml.

I am trying to set the text of a textView, however, whenever I do so, an error pops up

I have a textView, but when I try to set it's value to an EditText, it says that the textView is final. When I change it to not be final, an error occurs stating that textView needs an int. Why would it do this, and how can I change it so that it will take in the text in EditText? Here is the code for the class where I am trying to set the value for the textView:
public class MainScreen extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_screen);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
R.id.textView12 = R.id.editText3;
}
}
Here is the xml activity where textView is created:

What is happening? Thanks!

Instead of
R.id.textView12 = R.id.editText3;
Use
Textview tv =(TextView)findviewbyid(R.id.textView12);
EditText et =(EditText) findviewbyid(R.id.editText3);
to set content of edittext to textview use
tv.setText(et.getText().toString());
This Might Help You Out...

Reason
you are doing the set of text wrongly
R.id.textView12 = R.id.editText3;
this is trying to manipulate the ids in the android app,
QuickFix
instead use:
textView.setText(editTextString);

Textview textView12=(TextView)findviewbyid(R.id.textView12);
EditText editText3=(EditText)findviewbyid(R.id.editText3);
here is your answer
String text=textView12.getText().toString();
editText3.setText(text);
or
editText3.setText(textView12.getText().toString());
i hope this solves your problem

R.id.textView12 = R.id.editText3;
If this is how you are setting the text of EditText in TextView, it is wrong.
To set text in TextView you have to use setText() method.
example;
//Refering to you edit text
EditText editText = (EditText) findViewById(R.id.editText3);
//Refering to you TextView
TextView textView = (TextView) findViewById(R.id.textView12);
//getting text from edit text
String editTextString = editText.getText();
//setting text to TextView
textView.setText(editTextString);
try this, this will work.
and I recommend you to learn the basics of android/java programming.

So all expect here,anybody can help me on this???
Thank in advance

Add
Button registerScreen = (Button) findViewById(R.id.btnLogin);
Button loginScreen = (Button) findViewById (R.id.btnRegister);
instead of
Button registerScreen = (Button) findViewById(R.id.link_to_register);
`Button loginScreen = (Button) findViewById (R.id.link_to_login);`
you are casting the ID's of textViews instead of buttons.
OR
Change the ID name of buttons in main.xml ..

Your local variable loginScreen is of type Button, but you are calling findViewById() with the id of a TextView. Use R.id.btnRegister if you really want to hook the button before the text field.

when i run eclipse's emulator, the page receipt.xml only display 1 checkbox value even if i checked on many checkbox.
help plz....tq
i tick on the checkbox Ayam Masak kurma and daging masak merah....
the output turn to be this way....
Ayam Masak Kurma
Daging Masak Merah
there are lot of spaces there...can u help me...i cannot upload the image of the emulator here...it says that i must get 10 point to post images....

The white spaces between your textviews are textviews that arent hidden, try to hide them when you have no data for them like:
if(nsPutih==true) {
tvOutput1.setText("Nasi Putih");
tvOutput1.setVisibility(View.VISIBLE);
} else {
tvOutput1.setVisibility(View.GONE);
}
However this is bad practice, you should try to dynamically create the textviews by putting them in a ListView. Also try to pass the data to the activity using a Map of objects.

with your intent try to pass your values with putextra and getextra method it will work

Develop Reference

Java is a programming language and computing platform first released by Sun Microsystems in 1995.

Android XML file preventing Activity to open - java

Did you added the activity in AndroidManifest.xml? Every activity need to be added into the manifest file. for example: <activity android:name=".HelloGoogleMaps" android:label="#string/app_name"/>
