I have three Linearlayout inside a Linearlayout

<LinearLayout
        android:orientation="horizontal"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <LinearLayout
            android:orientation="vertical"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:gravity="center"
            android:id="@+id/l1"
            android:layout_alignParentTop="true"></LinearLayout>

        <LinearLayout
            android:orientation="vertical"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:gravity="center"
            android:id="@+id/l2"
            android:layout_alignParentTop="true"></LinearLayout>

        <LinearLayout
            android:orientation="vertical"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:gravity="center"
            android:id="@+id/l3"
            android:layout_alignParentTop="true"></LinearLayout>
    </LinearLayout>

And I’m putting one ImageButton within each of the layout so

if(l==1){
                layout1.addView(btCategoria);
                layout1.addView(txtCategoria);
                Log.e("l1","entrou "+txtCategoria.getText());
                l=2;
            }else if(l==2){
                layout2.addView(btCategoria);
                layout2.addView(txtCategoria);
                Log.e("l2","entrou "+txtCategoria.getText());
                l=3;
            }else if(l==3){
                layout3.addView(btCategoria);
                layout3.addView(txtCategoria);
                Log.e("l3","entrou "+txtCategoria.getText());
                l=1;
            }

btCategoriaand the ImageButton and the txtCategoria and a TextView

but the first is not getting on the same straight as the rest

wanted to know why the first image is above the other next

with this gridview will work more he has it android:columnWidth="200dp", I wanted to know if there is no way to define it because if you put a specific size will be bad depending on the cell right . 

<GridView
    android:id="@+id/grid"
    android:layout_width="wrap_content"
    android:layout_height="fill_parent"
    android:layout_below="@+id/spinner_widget"
    android:cacheColorHint="@color/abc_search_url_text_holo"
    android:columnWidth="200dp"
    android:gravity="center"
    android:numColumns="3"
    android:stretchMode="spacingWidth" />
android

  • Ever tried to use android:gravity="top" in the layout containing the 3?

  • 1

    Ilgner, does a Gridview not suit your layout better than mounting that Grid in hand?

  • and that the grid does not work for every type of cell phone

  • I highly recommend you use a GridView and let the system control the best way to present the images/information. And, in addition, you will have more control of the layout of each item on your grid. The GridView is available from API 1 http://developer.android.com/guide/topics/ui/layout/gridview.html and has several examples of how to implement it!

  • go take a look , and that the grid I tried didn’t work

  • I made a change in the question , because there is an item there that goes from the problem depending on the mobile , It may get too big or even too small

You can set the size of each item in your GridView calculating by device size (inside your Adapter):

int size;

//Recuperando a quantidade de colunas que você declarou para seu GridView
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
    size = getColumnSize();
} else {
    try {
        Field field = seuGridView.getClass().getDeclaredField("mColumnWidth");
        field.setAccessible(true);
        size = field.getInt(seuGridView);
    } catch (Exception ignored) {
        size = 0;
    }
}

// Fazendo o calculo para definir o melhor tamanho para cada item do seu GridView.
if (size <= 0) {
    float density = getApplicationContext().getResources().getDisplayMetrics().density;
    size = Math.round((float) 200 * density);
}

RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(size, RelativeLayout.LayoutParams.WRAP_CONTENT);
//definindo a largura máxima para sua imagem (ou em todo o seu layout)
suaImagem.setLayoutParams(params);

Don’t forget to add the attribute scaleType and adjusteViewBounds in his ImageView:

<ImageView
    android:id="@+id/imgPhotoGalleryItem"
    android:layout_width="wrap_content"
    android:scaleType="centerCrop"
    android:adjustViewBounds="true"
    android:layout_height="wrap_content"/>
