I am new on android. I have just made my first app. But as I run my my app on android emulator, it does not run. App compiled without any error, but on emulator it's showing that unfortunately app is stopped.
This is the java code:
package com.example.kartikeya;
import android.graphics.Color;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity implements View.OnClickListener{
double x,y;
static int op=0;
double result;
TextView textView = new TextView(this);
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView();
Button button = (Button) findViewById(R.id.button);
button.setOnClickListener(this); // calling onClick() method
Button button2 = (Button) findViewById(R.id.button2);
button2.setOnClickListener(this);
//Button button3 = (Button) findViewById(R.id.button3);
// button3.setOnClickListener(this);
textView = (TextView) findViewById(R.id.textView);
textView.setOnClickListener(this);
}
private void setContentView() {
}
#Override
public void onClick(View v) {
switch (v.getId()) {

Your problem is this line TextView textView = new TextView(this);
You are trying to call setText() on this view in your onClick methods, but this view hasn't been inflated. You have to inflate the view before you can manipulate it, just like you did with Button button = (Button) findViewById(R.id.button);
So in your onCreate() you would want to put in textView = (TextView) findViewById(R.id.your_text_view_id); and get rid of your TextView textView = new TextView(this); line -- just make it TextView textView;

Error when trying to add splash screen - android app

I'm an android newbie
I was following this tutorial Android splash screen howto, it's a little outdated, but anyways.
I just add the new layout file splash.xml into res/layout, and then the image into drawable/mdpi, then I change the main image into MainActivity.java, ie:
setContentView(R.layout.activity_main);
to
setContentView(R.layout.splash);
Being activity_main the name of the default layout, activity_main.xml, and splash the name of the other layout called splash.xml.
But application stops, says the application has unfortunately stopped, and I can't even access it.
I don't know what am I missing here, here's the interesting code on MainActivity.java:
protected void onCreate(Bundle savedInstanceState)
{
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
getWindow().setFormat(PixelFormat.TRANSLUCENT);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(
WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.splash);
relativeLayout=(RelativeLayout) findViewById(R.id.containerImg);
relativeLayout.setDrawingCacheEnabled(true);
cameraSurfaceView = (SurfaceView)
findViewById(R.id.surfaceView1);
// cameraSurfaceView.setLayoutParams(new FrameLayout.LayoutParams(640, 480));
cameraSurfaceHolder = cameraSurfaceView.getHolder();
cameraSurfaceHolder.addCallback(this);
// cameraSurfaceHolder.setType(SurfaceHolder.
// SURFACE_TYPE_PUSH_BUFFERS);
btnCapture = (Button)findViewById(R.id.button1);
btnCapture.setOnClickListener(new OnClickListener()
{
#Override
public void onClick(View v)
{
// TODO Auto-generated method stub
camera.takePicture(cameraShutterCallback,
cameraPictureCallbackRaw,
cameraPictureCallbackJpeg);
}
});

<LinearLayout

android:layout_height="fill_parent">
<ImageView
android:src="#drawable/splash"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:scaleType="fitXY"/>
</LinearLayout>
Any ideas?
Maybe I should use the same activity_main.xml for this purposes, not really sure...
Thanks in advance!

these are the views present in your activity_main xml file.. when you change your layout file why you are accessing these?

.com.process stopped unexpectedly in Android emulator and mobile

I am trying to make a simple android app that will add two numbers and display the output.However, I am getting the following error continuously.
"calculator.com.process stopped unexpectedly"
I used API 10 for rendering layout and API 17 as compiler and Target SDK.
Could post the code finally after all these trouble.
This is the code of main_activity.java
package com.example.calculator;

import android.view.Menu;
import android.view.MenuItem;

double total=x+y;
Display.setText("Sum is"+total);
}
});

You are having problem at line no-27
Caused by: java.lang.ClassCastException: android.widget.RelativeLayout
01-24 16:06:39.950: E/AndroidRuntime(1130): at com.example.calculator.MainActivity.onCreate(MainActivity.java:27)
Change the relativeLayouts Id in the xml file.
It should not be same as for the add button.
android:id="#+id/relativeLayout"
Change it as above.
Two id in the same layout cannot be same.
Your add button and the relative layout is having the same id,.
And during the findViewById(), relative layout is being caste in the Button.
That's why class cast exception is coming.
Edit:
I compiled your code:-
the next mistake you have made is-
txtNum1=(EditText) findViewById(R.id.Num2);
It should be
txtNum2=(EditText) findViewById(R.id.Num2);
Mistake-You are not assigning the reference to the second edittext.

this is the error
java.lang.ClassCastException: android.widget.TextView
check your line 24 and see if you cast the right widget in java -(xml), this error means incompatible cast widget lol...
if everything seems correct-(mean widgets are cast in java to with their respective class) then clean rebuild and restart..
EDIT: It worked.. you've solved it but there is a new error which is
java.lang.NumberFormatException:
its because of this on these lines
ivalue1 = Integer.parseInt(strvalue1);
ivalue2 = Integer.parseInt(strvalue2);
ioperator = Integer.parseInt(stroperator);
so change these to this
Integer.valueOf(strvalue1); do that as follows
and also looking at your codes.. your string values are pullled from the edittext during oncreate which means when the app starts in oncreate before the Onresume(which is called when the app shows on the), and during oncreate the user cant flirt with your app, and going further to input values, so at the end your strings are empty when you pull from the edittext, so basically what im saying is remove these lines
strvalue1 = value1.getText().toString();
and put them in the click events ... i am lucid enough to you??..
EDIT2: OVERALL CODE
for button click
ok.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
strvalue1 = value1.getText().toString();
strvalue2 = value2.getText().toString();
stroperator = myoperator.getText().toString();
ivalue1 = Integer.valueOf(strvalue1);
ivalue2 = Integer.valueOf(strvalue2);
if (stroperator.equals("+")) {
Toast.makeText(MainActivity.this, "If is running", Toast.LENGTH_LONG).show();
}
}
});

remove ioperator = Integer.parseInt(stroperator); from the code.I think Your trying to convert the operator to Integer.

ioperator = Integer.parseInt(stroperator);
if you mean operator like this +,-,/,* , you only can convert to thr char or stay in string and do something like this:
private int plus(int ivalue1 , int ivalue2 , String operator ){
if(operator.equal("+")){
return ivalue1 + ivalue2;
}
return 0;
}

Android Dev: ClassCastException Error
