如何动态地在TableLayout中绘制列

Question

如何动态地在TableLayout中绘制列，就像它们在图像中一样。

我想通过一个类的对象来创建表。

Answer 1

我将与ImageView的宽度match_parent工作你需要改变宽度

<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> 

在XML文件中

也使按钮与坐的onClick ATTR的按钮

现在与活动工作做出参数tableLayout

private TableLayout t1; 

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); 

的onClick方法中 申报的TableRow

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

现在我们让图像视图的实例

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

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 

后置ATTR图像视图的实例我们会L个上路的ImageView的划船

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

最后，我们将添加的TableRow到TableLayout

t1.addViwe(tr); 

没有运行该应用程序 当你点击链接，您将添加一行 你可以使用里面像循环验证码for循环或while循环 好运
