    <p>I'm trying to create an application such that when I click on a button in the 1st layout, it will extract the text from an EditText and place that value into a TextView from the 2nd layout. However, it seems that the application will crash because of the setText for the TextView.</p> <p>I didn't put the logCat as it doesn't tell much. I believe that the error comes from the setText part. But I have no idea on how to fix that part, or maybe that my way of coding is wrong. Hope that someone will help me. Thanks in advance. </p> <pre><code>&lt;TextView android:id="@+id/showtitle" android:layout_marginTop="1dip" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textSize="15sp" android:textStyle="bold" /&gt; &lt;TextView android:id="@+id/showtemplate" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@+id/showtitle" android:layout_alignLeft="@+id/showtitle" android:paddingBottom="4dip" android:includeFontPadding="false" android:textSize="15sp" android:textStyle="normal" /&gt; </code></pre> <p> Below is my java code:</p> <p>import android.os.Bundle; import android.view.View; import android.widget.TextView; import android.widget.EditText; import android.widget.Button; import android.widget.Toast;</p> <pre><code>import android.app.Activity; public class AndroidGroupSMS extends Activity{ private EditText title; private EditText template; private Button btnsave; private Button btnload; private TextView text,text2; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); title = (EditText) findViewById(R.id.title); template = (EditText) findViewById(R.id.template); btnsave = (Button) findViewById(R.id.save); btnload = (Button) findViewById(R.id.load); text = (TextView) findViewById(R.id.showtitle); text2 = (TextView) findViewById(R.id.showtemplate); btnsave.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { // TODO Auto-generated method stub String sTitle = title.getText().toString(); String sTemplate = template.getText().toString(); if(sTitle.length() &gt; 0 &amp;&amp; sTemplate.length() &gt; 0) { //this is where i'm setting the text extracted from the edittext boxes text.setText(sTitle.toString()); text2.setText(sTemplate.toString()); } else Toast.makeText(getBaseContext(),"Please enter the title and template" + "", Toast.LENGTH_SHORT).show(); } }); } </code></pre> <p>I have no idea how to read this.

    2. COWith something like this, I'm afraid if the logCat doesn't tell you much, you're not reading it right.

    3. COMy wild guess would be that something somewhere is null when you try to use it, logcat will tell you and us more :)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
