동적레이아웃(DynamicLayout)

Margin, Padding

ㆍ setPadding

ㆍ setMargins

ㆍ leftMargin, rightMargin, topMargin, bottomMargin

간단하게

 Padding과 Margin 알아보기

Default Padding

Padding 값 증가

가운데 o버튼 기준

Default Margin

Margin 값 증가

setPadding(left, top, right, bottom)

그냥 setPadding 하고

주면 끝난다

첫번째,

left, top Padding : 30

right, bottom Padding : 0

public class MainActivity extends AppCompatActivity
{
    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        //setContentView(R.layout.activity_main);
        LinearLayout ll = new LinearLayout(this);
        Button btn = new Button(this);
        btn.setText("Hello");
        btn.setPadding(30, 30, 0, 0);

        ll.addView(btn);
        setContentView(ll);
    }
}

두번째,

전체 Padding : 50

public class MainActivity extends AppCompatActivity
{
    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        //setContentView(R.layout.activity_main);
        LinearLayout ll = new LinearLayout(this);
        Button btn = new Button(this);
        btn.setText("Hello");
        btn.setPadding(50, 50, 50, 50);

        ll.addView(btn);
        setContentView(ll);
    }
}

setMargins(left, top, right, bottom)

LayoutParams를 추가해서

setMargins 값을 설정해 준후에

button에 적용시킨다

첫번째,

top Margin : 100

public class MainActivity extends AppCompatActivity
{
    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        //setContentView(R.layout.activity_main);
        LinearLayout ll = new LinearLayout(this);
        Button btn = new Button(this);
        btn.setText("Hello");

        LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(
                                           ViewGroup.LayoutParams.WRAP_CONTENT,
                                           ViewGroup.LayoutParams.WRAP_CONTENT);
        lp.setMargins(0,100,0,0);
        btn.setLayoutParams(lp);

        ll.addView(btn);
        setContentView(ll);
    }
}

두번째,

top Margin : 100

left Margin : 200

public class MainActivity extends AppCompatActivity
{
    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        //setContentView(R.layout.activity_main);
        LinearLayout ll = new LinearLayout(this);
        Button btn = new Button(this);
        btn.setText("Hello");

        LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(
                                           ViewGroup.LayoutParams.WRAP_CONTENT,
                                           ViewGroup.LayoutParams.WRAP_CONTENT);
        lp.setMargins(200,100,0,0);
        btn.setLayoutParams(lp);

        ll.addView(btn);
        setContentView(ll);
    }
}

결과화면

leftMargin, rightMargin, topMargin, bottomMargin

따로 주는 것도

가능하다

top Margin : 200

left Margin : 200

public class MainActivity extends AppCompatActivity
{
    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        //setContentView(R.layout.activity_main);
        LinearLayout ll = new LinearLayout(this);
        Button btn = new Button(this);
        btn.setText("Hello");

        LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(
                                           ViewGroup.LayoutParams.WRAP_CONTENT,
                                           ViewGroup.LayoutParams.WRAP_CONTENT);
        //lp.setMargins(200,100,0,0);
        lp.leftMargin = 200;
        lp.topMargin = 200;
        btn.setLayoutParams(lp);

        ll.addView(btn);
        setContentView(ll);
    }
