如何基于尺寸显示在表的行图像 [英] How to show image in table row based on size

问题描述

有。现在基于图像的大小，是指：如果图像适合1细胞是指1细胞，其他大手段根据大小2细胞或4细胞（我知道这将有多少细胞占据）

Have 2x2 grid(Dynamic using TableLayout) need to show image on that. now based on image size, means-- if image fit for 1 cell means 1 cell,else big means 2 cells or 4 cells based on size( I know how many cells it will occupy)

我可以在1单元格显示图像，但问题是，如果图像需要2细胞（第1列）如何能够在2细胞显示图像（出令人不安的网格）

i can show image in 1 cell, but problem is if image need 2 cells(1st column) how can show image in 2cell(With out disturbing the grid)

推荐答案

在不干扰电网，我看到了解决方法是动态设置图像在 TableLayout <顶部 / code>。
然后你就可以存档这样的：

Without disturbing the grid, the workaround I see is to dynamically set image on top of your TableLayout. Then you can archive this:

我上传的测试项目中的code 这里

I've uploaded the code of the test project here;

您初始化 overlappingImage ，一旦你需要将图像设置为你的手机 - 你只需根据你想要的细胞数量将它添加到布局和设置高度和宽度PARAMS填写。

You initialize overlappingImage and once you need to set image to your cell - you just add it to the layout and setting height and width params based on number of cells you want to fill.

TableLayout 动态生成，细胞的布局XML：

TableLayout generates dynamically, the cell's layout xml:

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_height="wrap_content"
    android:layout_width="wrap_content">
    <View
            android:layout_margin="4dp"
            android:background="#aacc00"
            android:layout_height="40dp"
            android:layout_width="40dp"/>
</FrameLayout>

的活动的布局：

The Activity's layout:

<?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:id="@+id/container"
    android:padding="16dp"
    android:orientation="vertical"
    app:layout_behavior="@string/appbar_scrolling_view_behavior">

    <TableLayout
        android:id="@+id/tableLayout"
        android:layout_width="match_parent"
        android:layout_height="280dp"/>

    <LinearLayout
        android:id="@+id/buttonsLinearLayout"
        android:layout_below="@+id/tableLayout"
        android:layout_marginTop="16dp"
        android:orientation="horizontal"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
        <Button
            android:text="1x1"
            android:id="@+id/button11"
            android:onClick="onClick11"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />
        <Button
            android:text="4x1"
            android:id="@+id/button21"
            android:onClick="onClick41"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />
        <Button
            android:text="2x3 at (2;2)"
            android:id="@+id/button12"
            android:onClick="onClick32"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />
        <Button
            android:text="2x2"
            android:id="@+id/button22"
            android:onClick="onClick22"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />
    </LinearLayout>
</RelativeLayout>

和活动code处理按钮点击＆安培;生成表：

And the Activity code to handle button clicks & generates table:

public class MainActivity extends AppCompatActivity {

    RelativeLayout container;
    int cellWidth = 0, cellHeight = 0;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        TableLayout tableLayout = (TableLayout) findViewById(R.id.tableLayout);
        tableLayout.setStretchAllColumns(true);
        for (int i = 0; i < 4; i++) {
            TableRow tableRow = new TableRow(this);
            for (int j = 0; j < 10; j++) {
                LayoutInflater layoutInflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                View cell = layoutInflater.inflate(R.layout.table_cell, null, false);
                if (cellHeight == 0 ) {
                    cell.measure(View.MeasureSpec.UNSPECIFIED, View.MeasureSpec.UNSPECIFIED);
                    cellWidth = cell.getMeasuredWidth();
                    cellHeight = cell.getMeasuredHeight();
                }

                tableRow.addView(cell);
            }

            tableLayout.addView(tableRow);
        }

        container = (RelativeLayout)findViewById(R.id.container);
        overlappingImage = new ImageView(this);
        overlappingImage.setScaleType(ImageView.ScaleType.FIT_XY);
    }

    ImageView overlappingImage;

    private void restoreTableLayout() {
        container.removeView(overlappingImage);
    }

    public void onClick11(View view) {
        restoreTableLayout();
        RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(cellWidth, cellHeight);
        overlappingImage.setLayoutParams(params);
        overlappingImage.setImageResource(R.drawable.horizontal_cat);
        container.addView(overlappingImage);
    }

    public void onClick41(View view) {
        restoreTableLayout();
        RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(cellWidth*4, cellHeight);
        overlappingImage.setLayoutParams(params);
        overlappingImage.setImageResource(R.drawable.horizontal_cat);
        container.addView(overlappingImage);
    }

    public void onClick32(View view) {
        restoreTableLayout();
        RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(cellWidth*3, cellHeight*2);
        params.setMargins(cellWidth*2, cellHeight*2, 0 ,0);
        overlappingImage.setLayoutParams(params);
        overlappingImage.setImageResource(R.drawable.vertical_cat);
        container.addView(overlappingImage);
    }

    public void onClick22(View view) {
        restoreTableLayout();
        RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(cellWidth*2, cellHeight*2);
        overlappingImage.setLayoutParams(params);
        overlappingImage.setImageResource(R.drawable.horizontal_cat);
        container.addView(overlappingImage);
    }
}

我希望它可以帮助。
