Closed 5 years ago.
I tried to add data to sqlite, but when I clicked Add Button error appear and my app closed. I don't understand, so many wasted hours for looking the solution by myself..
here is my java code, AddSampleActivity.java
package com.example.mangan;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
public class AddSampleActivity extends AppCompatActivity {
DatabaseHelper myDb;
EditText editNama, editJarak, editRating , editHarga;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_add_sample);
editNama = (EditText) findViewById(R.id.nama);
editJarak = (EditText) findViewById(R.id.jarak);
editRating = (EditText) findViewById(R.id.rating);
editHarga = (EditText) findViewById(R.id.harga);
myDb = new DatabaseHelper(this);
}
public void addData(View view) {
boolean isInserted = myDb.insertData(editNama.getText().toString(),
editJarak.getText().toString(),
editRating.getText().toString(),
editHarga.getText().toString() );
if(isInserted)
Toast.makeText(AddSampleActivity.this,"Data Inserted",Toast.LENGTH_LONG).show();
else
Toast.makeText(AddSampleActivity.this,"Data not Inserted",Toast.LENGTH_LONG).show();
}
}
my layout, activity_add_sample.xml

It seem that some content on addData method is the problem. I read another question, Getting IllegalStateException on button click, but the problem is little bit different..

Your edittext ids aren't correct. change them like below
editJarak = (EditText) findViewById(R.id.jarak_editText);
editRating = (EditText) findViewById(R.id.rating_editText);
editHarga = (EditText) findViewById(R.id.harga_editText);

Your edit text ids are wrong. Try this,
editNama = (EditText) findViewById(R.id.nama_editText);
editJarak = (EditText) findViewById(R.id.jarak_editText);
editRating = (EditText) findViewById(R.id.rating_editText);
editHarga = (EditText) findViewById(R.id.harga_editText);

There are two types of fragments: native ones and support/backport ones. You need to pick one type and stick with that.
As it stands, you are trying to use both:
You are using getFragmentManager() to add MyListFragment, indicating that MyListFragment extends android.app.ListFragment, not android.support.v4.app.ListFragment
You are using SupportMapFragment, which is a support/backport fragment

android.view.InflateException: Binary XML file line #36: Error inflating class fragment

I'm very new to Android Application Development. I know my problem might be simple one. but, I'm sure it is related to layout.
Here's my issue: There's is a listView in the Fragment. When I click the button the new Fragment is added to the ScrollView in the main Layout. When I start the activity one fragment is already added to the activity. So, when I change the rotation the application does not crash.
But, new Fragment is added in the ScrollView after clicking button. But this time when I change the Rotation of the device the Application crashes giving following the error in the end. Can you help me solve this problem. Error occurs only when I change rotaion otherwise app runs fine.

I added reply to the answers in comment section but no one is answering.

Well i had this kind of problem few days back but after changing the drawable in my layout it solved my problem because my drawable was too large that's why it's causing the problem.
You can check in your layout for drawable if it is large than change it with other small one.
I think this will end your problem.

In my case, updating the libraries worked for me.

Error inflating TextView class in Android Studio

I'm new to the Android SDK as well as Android Studio, but I'm familiar with programming. I have two activities that should be linked together, but for whatever reason my app crashes on launch due to an error in one of my XML files in regards to a TextView object I created. I have no idea what's going on from there. Any help is appreciated!
I'm 90% sure this file is the culprit. I can upload more code on request if you think that it is necessary. Below is the error.

You can't set textColor from a string resource. You can either hard code the value like #FFFFFF or save the value in colors.xml file
colors.xml
<color name="white">#FFFFFF</color>
Change
<TextView android:id="#+id/login_usernameHeading"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/username"
android:textSize="18sp"
android:textColor="#string/login_blue "/>
to
<TextView android:id="#+id/login_usernameHeading"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/username"
android:textSize="18sp"
android:textColor="#color/white" />
Similarly change the second TextView textColor to color resource.

I was facing similar error but reason was different. If you are trying to add TextView for Activity with name Splash it will give similar error.
