Android - Set text to TextView
In your layout XML:
<TextView
android:id="@+id/myAwesomeTextView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:text="Escriba el mensaje y luego clickee el canal a ser enviado"
android:textSize="20sp" />
Then, in your activity class:
// globally
TextView myAwesomeTextView = (TextView)findViewById(R.id.myAwesomeTextView);
//in your OnCreate() method
myAwesomeTextView.setText("My Awesome Text");
PUT THIS CODE IN YOUR XML FILE
<TextView
android:id="@+id/textview1"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
PUT THIS CODE IN YOUR JAVA FILE
// Declaring components like TextView globally is a good habit
TextView mTextView = (TextView) findViewById(R.id.textview1);
// Put this in OnCreate
mTextView.setText("Welcome to Dynamic TextView");
