Проблемы с динамическим добавлением дочернего элемента в GridLayout в android

Я делаю игру-головоломку. Я пытаюсь сделать GridLayout динамически размером 4x4. Я добавляю LinearLayout как ребенок, а затем ImageView внутри LinearLayout сетки через код. Планировка идет отлично. Но когда я помещаю ImageView в любую сетку, изображение принимает полную высоту и ширину сетки. Но он должен принимать только размер сетки, в которую он упал.

Здесь это мой код:

    public class PuzzleActivity extends AppCompatActivity {

    @Override
    public void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.puzzle_layout);

        findViewById(R.id.a0).setOnTouchListener(new MyTouchListener());
        findViewById(R.id.b0).setOnTouchListener(new MyTouchListener());
        findViewById(R.id.c0).setOnTouchListener(new MyTouchListener());
        findViewById(R.id.d0).setOnTouchListener(new MyTouchListener());
        findViewById(R.id.e0).setOnTouchListener(new MyTouchListener());
        GridLayout layout = (GridLayout) findViewById(R.id.gridLayout);
        layout.setRowCount(4);
        layout.setColumnCount(4);
        for (int i = 0; i < 4; i++) {
            GridLayout.Spec rowSpec = GridLayout.spec(i, 1,1);
            for (int j = 0; j < 4; j++) {
                GridLayout.Spec colSpec = GridLayout.spec(j, 1,1);
                LinearLayout linearLayout = new LinearLayout(this);
                linearLayout.setLayoutParams(new ViewGroup.LayoutParams(0,0));
                linearLayout.setOrientation(LinearLayout.HORIZONTAL);
                linearLayout.setId(R.id.row + i + R.id.col + j);

Вот как выглядит макет:

Но когда я опускаю изображение в любой из сетки его принимая полную высоту и ширину GridLayout:

Если я делаю создание статического GridLayout в layout.xml его работа отлично. Проблема возникает, когда я создаю динамический GridLayout.

Вот мой layout.xml, который я использовал раньше для создания статики GridLayout и это работало нормально. Но теперь я пытаюсь динамическое создание GridLayout через код, который дает мне проблемы:

2 ответа:

Я рекомендую вам использовать google flexbox-layout вместо support GridLayout. его гораздо более гибкий, а также стабильный и простой в использовании.

Подробнее об этом читайте в github.

Если вы хотите динамически добавлять детей, смотрите этот пример:

XML-макет:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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="match_parent"
    android:orientation="vertical">

    <com.google.android.flexbox.FlexboxLayout
        android:id="@+id/flexLayout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_centerInParent="true"
        android:paddingBottom="70dp"
        android:paddingEnd="20dp"
        android:paddingStart="20dp"
        android:paddingTop="70dp"
        app:alignContent="stretch"
        app:alignItems="stretch"
        app:flexDirection="row"
        app:flexWrap="wrap"/>

</RelativeLayout>

Код:

public class PuzzleActivity extends AppCompatActivity {

    @Override
    public void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.puzzle_dynamic);

        FlexboxLayout layout = (FlexboxLayout) findViewById(R.id.flexLayout);
        for (int i = 0; i < 4; i++) {
            for (int j = 0; j < 4; j++) {
                LinearLayout linearLayout = new LinearLayout(this);
                linearLayout.setLayoutParams(new ViewGroup.LayoutParams(0, 0));
                linearLayout.setOrientation(LinearLayout.HORIZONTAL);
                //linearLayout.setId(R.id.row + i + R.id.col + j);
                linearLayout.setGravity(Gravity.FILL_HORIZONTAL);
                linearLayout.setBackground(ContextCompat.getDrawable(this, R.drawable.layout_background));
                ImageView imageView = new ImageView(this);
                imageView.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
                imageView.setAdjustViewBounds(true);
                imageView.setScaleType(ImageView.ScaleType.FIT_XY);
                linearLayout.addView(imageView);

                FlexboxLayout.LayoutParams lp = new FlexboxLayout.LayoutParams(FlexboxLayout.LayoutParams.WRAP_CONTENT, FlexboxLayout.LayoutParams.WRAP_CONTENT);
                lp.setFlexGrow(1);

                if (j == 0)
                    lp.setWrapBefore(true);//notice to this!

                layout.addView(linearLayout, lp);
            }
        }
    }
}

Для добавления flexbox в проект кода поместите эту строку в зависимость gradle:

compile 'com.google.android:flexbox:0.3.0'

Посмотрите, где вы добавляете линейный макет к сетчатому виду в onCreate(). На ранней стадии вы устанавливаете параметры макета следующим образом:
LinearLayout linearLayout = new LinearLayout(this);
linearLayout.setLayoutParams(new ViewGroup.LayoutParams(0, 0));
Тем не менее, позже вы добавляете линейные макеты с другим набором параметров макета следующим образом:
GridLayout.LayoutParams myGLP = new GridLayout.LayoutParams();
myGLP.rowSpec = rowSpec;
myGLP.columnSpec = colSpec;
layout.addView(linearLayout, myGLP);
Это сведет на нет предыдущие параметры компоновки. Я предлагаю вам изменить код на следующий:
GridLayout.LayoutParams myGLP = new GridLayout.LayoutParams();
myGLP.rowSpec = rowSpec;
myGLP.columnSpec = colSpec;
myGLP.width = 0;
myGLP.height = 0;
layout.addView(linearLayout, myGLP);
Вы можете удалить предыдущий код.
