How set the android:gravity to TextView from Java side in Android

I can use android:gravity="bottom|center_horizontal" in xml on a textview to get my desired results, but I need to do this programmatically. My textview is inside a tablerow if that matters in a relativelayout.

I have tried:

LayoutParams layoutParams = new TableRow.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, Gravity.BOTTOM | Gravity.CENTER_HORIZONTAL);
labelTV.setLayoutParams(layoutParams);

But if I understand correctly, that would apply it to the tablerow, not the textview?

labelTV.setGravity(Gravity.CENTER | Gravity.BOTTOM);

Kotlin version (thanks to Thommy)

labelTV.gravity = Gravity.CENTER_HORIZONTAL or Gravity.BOTTOM

Also, are you talking about gravity or about layout_gravity? The latter won't work in a RelativeLayout.

This will center the text in a text view:

TextView ta = (TextView) findViewById(R.layout.text_view);
LayoutParams lp = new LayoutParams();
lp.gravity = Gravity.CENTER_HORIZONTAL;
ta.setLayoutParams(lp);

We can set layout gravity on any view like below way-

myView = findViewById(R.id.myView);
myView.setGravity(Gravity.CENTER_VERTICAL|Gravity.RIGHT);
 or
myView.setGravity(Gravity.BOTTOM);

This is equilent to below xml code

<...
 android:gravity="center_vertical|right"
 ...
 .../>

You should use textView.setGravity(Gravity.CENTER_HORIZONTAL);.

Remember that using

LinearLayout.LayoutParams layoutParams =new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
layoutParams2.gravity = Gravity.BOTTOM | Gravity.CENTER_HORIZONTAL;

won't work. This will set the gravity for the widget and not for it's text.

Use this code

        TextView textView = new TextView(YourActivity.this);
        textView.setGravity(Gravity.CENTER | Gravity.TOP);
        textView.setText("some text");

textView.setGravity(Gravity.CENTER | Gravity.BOTTOM);

This will set gravity of your textview.

Solved this by doing a few things, first getting the height of my TextView and diving it by the text size to get the total amount of lines possible with the TextView.

int maxLines = (int) TextView.getHeight() / (int) TextView.getTextSize();

After you get this value you need to set your TextView maxLines to this new value.

TextView.setMaxLines(maxLines);

Set the Gravity to Bottom once the maximum amount of lines has been exceeded and it will scroll down automatically.

if (TextView.getLineCount() >= maxLines) {
    TextView.setGravity(Gravity.BOTTOM);
}

In order for this to work correctly, you must use append() to the TextView, If you setText() this will not work.

TextView.append("Your Text");

The benefit of this method is that this can be used dynamically regardless of the height of your TextView and the text size. If you decide to make modifications to your layout this code would still work.
