如何动态地在TableLayout中绘制列

Question

如何在TableLayout中动态绘制列，就像它们在图像中一样。

我想传递一个类的对象来创建表。

Answer 1

我将使用ImageView width match_parent你需要改变宽度

<TableLayout
            android:id="@+id/t1"
            android:layout_width="match_parent"
            android:layout_height="wrap_content">

            <TableRow
                android:layout_width="match_parent"
                android:layout_height="match_parent">

                <ImageView
                   android:id="@+id/imageView"
                   android:layout_width="wrap_content"
                   android:layout_height="wrap_content"
                   android:layout_gravity="center"
                   app:srcCompat="@drawable/qr"/>

                <ImageView
                   android:id="@+id/imageView2"
                   android:layout_width="wrap_content"
                   android:layout_height="wrap_content"
                   android:layout_gravity="center"
                   app:srcCompat="@drawable/qr"/>

                <ImageView
                   android:id="@+id/imageView3"
                   android:layout_width="wrap_content"
                   android:layout_height="wrap_content"
                   android:layout_gravity="center"
                   app:srcCompat="@drawable/qr"/>
                <ImageView
                   android:id="@+id/imageView4"
                   android:layout_width="wrap_content"
                   android:layout_height="wrap_content"
                   android:layout_gravity="center"
                   app:srcCompat="@drawable/qr"/>
                <ImageView
                   android:id="@+id/imageView5"
                   android:layout_width="wrap_content"
                   android:layout_height="wrap_content"
                   android:layout_gravity="center"
                   app:srcCompat="@drawable/qr"/>
            </TableRow>

        </TableLayout>

同样在您的XML文件中创建按钮并坐在onClick attr上按钮

现在使用tableLayout的Activity make参数

private TableLayout t1;

on onCreate方法准备t1参数

t1 = (TableLayout)findViewById(R.id.t1);
t1.setColumnStretchable(0,true);
t1.setColumnStretchable(1,true);
t1.setColumnStretchable(2,true);
t1.setColumnStretchable(3,true);
t1.setColumnStretchable(4,true);

在onClick方法中声明TableRow

//you can declare Context with parameter and used instead of this
TableRow tr = new TableRow(this);

现在我们制作图像视图的实例

ImageView img1 = new ImageView(this);
ImageView img2 = new ImageView(this);
ImageView img3 = new ImageView(this);
ImageView img4 = new ImageView(this);
ImageView img5 = new ImageView(this);

现在我们设置attr作为图像视图的例子

img1.setImageResource(R.drawable.ic_favorite);
img1.setMaxWidth(50);
img1.setMinimumWidth(30);
img1.setMaxHeight(50);
img1.setMinimumHeight(30);
img1.setForegroundGravity(Gravity.CENTER); // this is work from API23

img2.setImageResource(R.drawable.ic_favorite);
img2.setMaxWidth(50);
img2.setMinimumWidth(30);
img2.setMaxHeight(50);
img2.setMinimumHeight(30);
img2.setForegroundGravity(Gravity.CENTER); // this is work from API23

img3.setImageResource(R.drawable.ic_favorite);
img3.setMaxWidth(50);
img3.setMinimumWidth(30);
img3.setMaxHeight(50);
img3.setMinimumHeight(30);
img3.setForegroundGravity(Gravity.CENTER); // this is work from API23

img4.setImageResource(R.drawable.ic_favorite);
img4.setMaxWidth(50);
img4.setMinimumWidth(30);
img4.setMaxHeight(50);
img4.setMinimumHeight(30);
img4.setForegroundGravity(Gravity.CENTER); // this is work from API23

img5.setImageResource(R.drawable.ic_favorite);
img5.setMaxWidth(50);
img5.setMinimumWidth(30);
img5.setMaxHeight(50);
img5.setMinimumHeight(30);
img5.setForegroundGravity(Gravity.CENTER); // this is work from API23

之后我们将imageView添加到行

tr.addView(img1);
tr.addView(img2);
tr.addView(img3);
tr.addView(img4);
tr.addView(img5);

最后我们将tableRow添加到TableLayout

t1.addViwe(tr);

没有运行应用程序当您单击按钮时，您将添加行，您可以在循环中使用此代码，例如for循环或while循环好运
