I want to my activity to have the number of buttons depending on the array size given. Consider an array s1[4]. So the size is 4. I Would like to have 4 buttons in my activity.How could I achieve it?
You can dynamically add button in availbale linear layout.
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/linear_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
</LinearLayout>
MainActivity.java
public void addButton(){
Button myButton = new Button(this);
myButton.setText("Push Me");
LinearLayout ll = (LinearLayout)findViewById(R.id.linear_layout);
LayoutParams lp = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
ll.addView(myButton, lp);
}
Add Dynamic Buttons to your LinearLayout
Try something like this
//the layout in which you want to add the button
LinearLayout layout = (LinearLayout) findViewById(R.id.your_lin_layout);
for(int i = 0; i<arrayName.length ; i++) {
//create the button
Button btn = new Button(this);
//set all your button attributes, like text color,background color etc. here
btn.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
btn.setText("YOUR BUTTON TEXT");
//Set onClickListener
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// define this method in your activity
onBtnClick(i);
}
});
//add the button to your linear layout
layout.addView(btn);
}
