Square Grid - XML

问题:

In my studies, I have to do an Android application that retrieves weather data from a weather station. These will be displayed in blocks. These blocks will depart on 4 columns and 2 rows.

So I wanted to create a square grid of 4 columns and 2 lines for the provision of the blocks.

Someone would have a solution to help me create this grid, please?

There are many options : 1. you can choose a recycler view with GridLayoutManager

<android.support.v7.widget.RecyclerView
  android:id="@+id/main_grid"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:padding="2dp"
  />

So inside activity you will do something like

mRecyclerView.setLayoutManager(new GridLayoutManager(getContext(), COLUMN_COUNT));

2. You choose grid view

<GridView
android:id="@+id/grid"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:drawSelectorOnTop="true"
android:horizontalSpacing="2dp"
android:numColumns="4"
android:padding="4dp"
android:stretchMode="columnWidth"/>

For fixed item size you should use

<android.support.v7.widget.GridLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:app="http://schemas.android.com/apk/res-auto"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  app:columnCount="4"
  app:orientation="horizontal"
  >

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Hello World!"
    />

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Hello World!"
    />

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Hello World!"
    />
  <TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Hello World!"
    />

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

Make sure you add this in your app gradle

compile 'com.android.support:gridlayout-v7:23.0.1'
