Programmatically Add View One Below Other in Relative Layout

Relative Layout adding views programmatically one below other not aligning correctly

I was using the index of the for loop as id for the textViews which I changed to make Android generate Id for it as below and it is working fine now as expected.

I changed the line

textView.setId(i)

to

textView.setId(ViewGroup.generateViewId())

Thanks.

Programmatically add view one below other in relative layout

Important: Remember to set the ID for each view.

RelativeLayout layout = new RelativeLayout(this);
RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
layout.setLayoutParams(layoutParams);

RelativeLayout.LayoutParams params1 = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
RelativeLayout.LayoutParams params2 = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
RelativeLayout.LayoutParams params3 = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
RelativeLayout.LayoutParams params4 = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);

TextView tv1 = new TextView(this);
tv1.setId(1);
tv1.setText("textView1");

TextView tv2 = new TextView(this);
params2.addRule(RelativeLayout.RIGHT_OF, tv1.getId());
tv2.setId(2);
tv2.setText("textView2");

TextView tv3 = new TextView(this);
params3.addRule(RelativeLayout.BELOW, tv1.getId());
tv3.setId(3);
tv3.setText("textView3");

TextView tv4 = new TextView(this);
params4.addRule(RelativeLayout.RIGHT_OF, tv3.getId());
params4.addRule(RelativeLayout.ALIGN_BOTTOM, tv3.getId());
tv4.setId(4);
tv4.setText("textView4");

layout.addView(tv1, params1);
layout.addView(tv2, params2);
layout.addView(tv3, params3);
layout.addView(tv4, params4);

Adding a view between 2 views when one view is aligned to the bottom programmatically

Try this

    RelativeLayout rlmain= (RelativeLayout) findViewById(R.id.rlMain);

    RelativeLayout rA=new RelativeLayout(MainActivity.this);
    RelativeLayout.LayoutParams layoutA = new RelativeLayout.LayoutParams(
            RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
    rA.setId(1);
    rA.setBackgroundColor(getResources().getColor(R.color.blue));
    layoutA.addRule(RelativeLayout.ALIGN_PARENT_TOP, rlmain.getId());
    rA.setLayoutParams(layoutA);

    TextView tvA=new TextView(MainActivity.this);
    RelativeLayout.LayoutParams tvParamA = new RelativeLayout.LayoutParams(
            RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
    tvA.setText("This is Layout 1");
    tvA.setLayoutParams(tvParamA);
    rA.addView(tvA);

    RelativeLayout rC=new RelativeLayout(MainActivity.this);
    RelativeLayout.LayoutParams layoutC = new RelativeLayout.LayoutParams(
            RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
    layoutC.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM,rlmain.getId());
    rC.setId(3);
    rC.setLayoutParams(layoutC);
    rC.setBackgroundColor(getResources().getColor(R.color.gray));

    TextView tvC=new TextView(MainActivity.this);
    RelativeLayout.LayoutParams tvParamC = new RelativeLayout.LayoutParams(
            RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
    tvC.setText("This is Layout 3");
    tvC.setLayoutParams(tvParamC);
    rC.addView(tvC);

    RelativeLayout rB=new RelativeLayout(MainActivity.this);
    RelativeLayout.LayoutParams layoutB = new RelativeLayout.LayoutParams(
            RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT);
    layoutB.addRule(RelativeLayout.BELOW, rA.getId());
    layoutB.addRule(RelativeLayout.ABOVE, rC.getId());
    rB.setId(2);
    rB.setLayoutParams(layoutB);
    rB.setBackgroundColor(getResources().getColor(R.color.orange));

    ScrollView scroll=new ScrollView(MainActivity.this);
    RelativeLayout.LayoutParams scrollB = new RelativeLayout.LayoutParams(
            RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT);
    scroll.setLayoutParams(scrollB);
    rB.addView(scroll);

    rlmain.addView(rA);
    rlmain.addView(rB);
    rlmain.addView(rC);

rlMain in above code is the RelativeLayout declared in xml file.

Hope this may help you!
