Question

我有一排按钮但是超出了屏幕的宽度。我试着让按钮变小但是没有效果。它有一排11个圆形按钮。我能做什么？最后我想制作一个11乘11的网格，有关如何做到这一点的更好的建议，然后是一个巨大的布局xml？

main.xml中

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

Answer 1

您可以将所有按钮包裹成如此对齐的线性布局。

<LinearLayout 
    android:layout_width="0dp"
    android:layout_height="match_parent">    
    <Button 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content"
      android:layout_weight="1" 
      android:text="O"
      android:id="@+id/button1" 
      android:background="@drawable/roundedbutton"/>
    <Button 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content"
      android:layout_weight="1" 
      android:text="O"
      android:id="@+id/button1" 
      android:background="@drawable/roundedbutton"/>

</LinearLayout>

我发现你的问题实际上有两部分。你可以用两个嵌套for循环手动创建网格..

Answer 2

gridView.xml

<?xml version="1.0" encoding="utf-8"?>
<GridView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/gridView1"
    android:numColumns="auto_fit"
    android:gravity="center"
    android:columnWidth="100dp"
    android:stretchMode="columnWidth"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >
</GridView>

item.xml

<Button 
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="O"
android:id="@+id/grid_item_label"
android:layout_column="1" 
android:background = "@drawable/roundedbutton"/>

自定义按钮适配器类...您可以将其用作内部类

public class ButtonAdapter extends BaseAdapter {
        private Context context;
        private final String[] buttonTextValues;

    public ButtonAdapter(Context context, String[] buttonTextValues) {
        this.context = context;
        this.buttonTextValues = textViewValues;
    }

    public View getView(int position, View convertView, ViewGroup parent) {

        LayoutInflater inflater = (LayoutInflater) context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        View gridView;

        if (convertView == null) {

            gridView = new View(context);

            // get layout from mobile.xml
            gridView = inflater.inflate(R.layout.item, null);

            // set value into textview
            Button btn= (Button) gridView
                    .findViewById(R.id.grid_item_label);
            btn.setText(buttonTextValues[position]);  
        } else {
            gridView = (View) convertView;
        }

        return gridView;
    }

    @Override
    public int getCount() {
        return buttonTextValues.length;
    }

    @Override
    public Object getItem(int position) {
        return null;
    }

    @Override
    public long getItemId(int position) {
        return 0;
    }

}

活性：

public class ButtonGridView extends Activity {

        GridView gv;
        String[] buttonText = {"1", "2"}; //and so on to 11*11

        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.gridView);
            gv =(GridView)findViewById(R.id.gridView1);
            gv.setAdapter(new ButtonAdapter(this,buttonText));
        }
    }

另请注意，您可以根据需要传递任何信息以使用构造函数进行适配，并确定该按钮将具有任何颜色文本或任何您想要的...
