Align Android GridLayout

Question

I need that the GridLayout align the views like this (the light blue icons and text are the view in the GridLayout):

But my GridLayout align like this:

And if I set app:layout_columnWeight="1" and app:layout_rowWeight="1", my GridLayout align like this:

My GridLayout xml:

<android.support.v7.widget.GridLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginTop="18dp"
            app:columnCount="7">

            <com.motivapp.motivapp.customview.KeywordView
                android:id="@+id/keyword1"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                keyword:text="Trilha"/>

            <com.motivapp.motivapp.customview.KeywordView
                android:id="@+id/keyword2"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                keyword:text="Mergulho"/>

            <com.motivapp.motivapp.customview.KeywordView
                android:id="@+id/keyword3"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                keyword:text="Praia"/>

            <com.motivapp.motivapp.customview.KeywordView
                android:id="@+id/keyword4"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                keyword:text="Festas"/>

            <com.motivapp.motivapp.customview.KeywordView
                android:id="@+id/keyword5"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                keyword:text="Parque de Diversões"/>

            <com.motivapp.motivapp.customview.KeywordView
                android:id="@+id/keyword6"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                keyword:text="Relaxar"/>

            <com.motivapp.motivapp.customview.KeywordView
                android:id="@+id/keyword7"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                keyword:text="Esportes Radicais"/>

            <com.motivapp.motivapp.customview.KeywordView
                android:id="@+id/keyword8"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                keyword:text="Acampamento"/>

            <com.motivapp.motivapp.customview.KeywordView
                android:id="@+id/keyword9"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                keyword:text="Off Road"/>

            <com.motivapp.motivapp.customview.KeywordView
                android:id="@+id/keyword10"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                keyword:text="Passeio de Barco"/>

            <com.motivapp.motivapp.customview.KeywordView
                android:id="@+id/keyword11"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                keyword:text="Restaurantes"/>

            <com.motivapp.motivapp.customview.KeywordView
                android:id="@+id/keyword12"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                keyword:text="Show / Festival"/>

            <com.motivapp.motivapp.customview.KeywordView
                android:id="@+id/keyword13"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                keyword:text="Resort / SPA"/>

            <com.motivapp.motivapp.customview.KeywordView
                android:id="@+id/keyword14"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                keyword:text="Locas Históricos"/>


        </android.support.v7.widget.GridLayout>

And the views inside GridView:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">

    <com.motivapp.motivapp.customview.DefaultTextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/keywordTextView"
        android:textSize="18sp"
        android:text="Keyword"
        android:textColor="#839EC5"
        android:layout_gravity="center_horizontal"/>

    <ImageView
        android:layout_width="130dp"
        android:layout_height="130dp"
        android:layout_gravity="center_horizontal"
        android:src="@drawable/keyword_button"
        android:id="@+id/keywordButton"/>

</LinearLayout>

It's a custom view, but now, it do nothing, only show a custom textview and a imageview... What I do to GridLayout align like the first image?

UPDATE:

It's near to solve my question... I change some things, and now only a view is not aligned.

I put app:layout_columnWeight="1" on all views of gridlayout, and changed the gravity and text width of custom view layout:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center_vertical|center_horizontal">

    <com.motivapp.motivapp.customview.DefaultTextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/keywordTextView"
        android:textSize="16sp"
        android:text="Keyword"
        android:textColor="#839EC5"
        android:gravity="center"/>

    <ImageView
        android:layout_width="120dp"
        android:layout_height="120dp"
        android:src="@drawable/keyword_button"
        android:id="@+id/keywordButton"/>

</LinearLayout>

How to center all this views? How to prevent that when textview have a big width and line break, he force the imageview go down and don't center align?

Answer 1

You can use custom GridView with android:numColumns="7" or you can use RecyclerView with GridLayoutManager with 7 columns You can use your custom layout for item view to define your text and image as below:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical">

    <TextView
        android:id="@+id/txtGridItem"
        android:layout_width="match_parent"
        android:gravity="center"
        android:layout_height="wrap_content" />

    <ImageView
        android:id="@+id/imgGridItem"
        android:layout_width="match_parent"
        android:layout_height="130dp" />
</LinearLayout>

Answer 2

Use RecyclerView instead of GridLayout and set count to 7.

Answer 3

Use this in xml

<GridView
                android:id="@+id/grid"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:columnWidth="100dp"
                android:gravity="center"
                android:numColumns="auto_fit"
                android:stretchMode="columnWidth" />

Answer 4

You can use RecyclerView with GridLayoutManager like this

GridLayoutManager mGridLayoutManager = new GridLayoutManager(context, 2, LinearLayoutManager.HORIZONTAL, false);

Set layout manager to adapter mRecyclerView.setLayoutManager(mGridLayoutManager);

Answer 5

this is occur because of the textview size is long thats why it take more space so kindly set width to match_parent in your textview if its not worked than reduce that text size.

Answer 6

Here's one way to do it. This assumes that you want the GridView centered in the parent. If it needs to be centered relative to something else, you will have to modify the code.

All I did was subclass onLayout and "translate" the grid view to a centered position.

public class GridViewCentering extends GridView
{
  public GridViewCentering (Context context, AttributeSet attrs)
  {
    super (context, attrs);
  }

  @Override
  protected void onLayout (boolean changed, int l, int t, int r, int b)
  {
    super.onLayout (changed, l, t, r, b);
    int parentW = ((ViewGroup)getParent ()).getMeasuredWidth();
    int w = getWidth ();
    int offset = (parentW - w) / 2;
    setTranslationX (offset);
  }
}

Answer 7

The Problem is that the views are not the same height when the text has one line or two. There are multiple possible solutions:

Best might be: Add layout_gravity="bottom" to each item inside the Gridlayout. If there is a view with two lines the spacing of the other views is added on top and the image (circle) is all at the same height.

If you want all rows to have the same height you could add android:minLines="2" to all the Textviews. But this would put a spacing between the text and the image for short texts.
