android programatically add customized button to a layout

Question

I want to programatically add buttons in android, the xml file for the button would be

<Button
android:textStyle="bold"
android:background="@drawable/blue"
android:textColor="@drawable/blue_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/funny_excuses"
android:id="@+id/funny"
android:paddingBottom="10dp"
android:paddingTop="10dp"
android:paddingLeft="6dp"
android:paddingRight="6dp"
android:textSize="25sp"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true" />

What is the best way to do it? I will only change the text for each new button.. And maybe I will have another button type, like with other background and textcolor..

Basically it is the same thing, you just need to apply a custom style using this stackoverflow.com/questions/2016249/… or setting the style programatically as well... — 2Dee

Also its possible to create this Button xml and inflate layout recource from code: button.xml:

<Button
 xmlns:android="http://schemas.android.com/apk/res/android"
 android:textStyle="bold"
 android:background="@drawable/blue"
 android:textColor="@drawable/blue_text"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:text="@string/funny_excuses"
 android:id="@+id/funny"
 android:paddingBottom="10dp"
 android:paddingTop="10dp"
 android:paddingLeft="6dp"
 android:paddingRight="6dp"
 android:textSize="25sp"
 android:layout_alignParentTop="true"
 android:layout_centerHorizontal="true" />

code:

    Button button = (Button) getLayoutInflater().inflate(R.layout.button, null);
    button.setText("Hello world");
    RelativeLayout ll = (RelativeLayout) findViewById(R.id.ll); //layout to add
    ll.addView(button);

This was exactly what I wanted to do, thanks. How can I set the android:layout_below= tag programatically so the button is added the as the last one?

you have to create LayoutParams and add rule, this link may help you: link also think about replacing to LinearLayout.

        <item name="android:layout_width">match_parent</item>
        <item name="android:textColor">#000000</item>
        <item name="android:textSize">20sp</item>

Create your button in your layout, then use yourButton.setVisibility(View.GONE); for hide it and use yourButton.setVisibility(View.VISIBLE); for make it visible.
