Right now I have the following code in "activity_main.xml" :
<Button
android:id="@+id/Table_Button_1_1"
android:layout_width="96dp"
android:layout_height="96dp"
android:layout_marginStart="5dp"
android:layout_marginTop="1dp"
android:text="@string/Table_Button_1_1"
android:textAllCaps="false"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<Button
android:id="@+id/Table_Button_1_2"
android:layout_width="96dp"
android:layout_height="96dp"
android:layout_marginStart="102dp"
android:layout_marginTop="1dp"
android:text="@string/Table_Button_1_2"
android:textAllCaps="false"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<Button
android:id="@+id/Table_Button_1_3"
android:layout_width="96dp"
android:layout_height="96dp"
android:layout_marginStart="199dp"
android:layout_marginTop="1dp"
android:text="@string/Table_Button_1_3"
android:textAllCaps="false"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
...
In the Java code it looks like this :
public class MainActivity extends AppCompatActivity
{
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button button_1_1 = findViewById(R.id.Table_Button_1_1);
button_1_1.setTypeface(Typeface.MONOSPACE);
button_1_1.setTextSize(23);
button_1_1.setText("2 \u24be\n\u2665 \u2709");
Button button_1_2 = findViewById(R.id.Table_Button_1_2);
button_1_2.setTypeface(Typeface.MONOSPACE);
button_1_2.setTextSize(23);
button_1_2.setText("a b\nc d");
With lots of buttons, I want to access them through an array of buttons, so I want my Java code to look like this :
public class MainActivity extends AppCompatActivity
{
Button myButton[]=new Button[6];
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
for (int i=0;i<6;i++)
{
Button myButton[i] = findViewById(R.id.Table_Button[i]); <-- Get the button Like this
myButton[i].setText("Text : "+i);
}
}
...
Yet, I don't know how to define the button array in activity_main.xml, so that in Java I can access them through findViewById(R.id.Table_Button[i]), I guess something like this :
<Button
android:id="@+id/Table_Button[6]" <--- ?
android:layout_width="96dp"
android:layout_height="96dp"
android:layout_marginStart="5dp"
android:layout_marginTop="1dp"
android:text="@string/Table_Button[6]" <--- ?
android:textAllCaps="false"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
This will also affect string.xml. What's the proper way to do it [ in both activity_main.xml & string.xml ] ?
Edit : Here is why my question is different from suggested previous question. The first half is similar [ how to access the buttons from java code ], but I want the buttons to be defined in the activity_main.xml, so at design time, I can see their layout, and locate which button is in which row,col. Therefore what I wanted the most is "How to define the button array in the activity_main.xml & string.xml" and be able to access them from the java code ?
