刷新tableLayout [英] Refresh tableLayout

问题描述

您好我有一个tableLayout和我填充ImageView的[] []使用嵌套循环的布局。目前我想点击一个ImageView的和重新排列ImageView的[] []的数据，那么刷新屏幕，以反映重排。有没有办法做到这一点？显然，我不能调用setContentView不止一次。

编辑：你可以看到这是code为onclick事件。我的setContentView在onCreate事件原来TableLayout（'TL'），不能在这里再次调用它。

 公共无效的onClick（视图v）{
    // TODO自动生成方法存根
    开关（v.getId（））{
    情况1：
        image_array = switchTile（image_array，2,1,0,0）;
        Toast.makeText（这一点，1点击！，Toast.LENGTH_LONG）.show（）;    }    tl.removeAllViewsInLayout（）;    的for（int i = 0; I＆LT;水平;我++）{
        的TableRow new_tr =新的TableRow（本）;
        new_tr.setLayoutParams（layout_image）;        对于（INT J = 0; J＆LT;水平; J ++）{
            new_tr.addView（image_array [I] [J]）;
        }
        tl.addView（new_tr）;
    }    tl.invalidate（）;}
 

解决方案

如果你想要做的就是四处移动的图像，你可以做对现有ImageViews setImageBitmap（）操作。您可以使用相同的位图和任何ImageViews显示他们请你。

Hi I have a tableLayout and am populating the layout with ImageView[][] using a nested for loop. I'm currently trying to click on an ImageView and rearrange the ImageView[][] data then refresh the screen to reflect the rearrangement. Is there a way to do this? Apparently I can't call the setContentView more than once.

Edit: you can see this is the code for the onclick event. I setContentView of the original TableLayout ('tl') in the onCreate event and can't call it again here.

public void onClick(View v) {
    // TODO Auto-generated method stub
    switch(v.getId()){
    case 1: 
        image_array = switchTile(image_array, 2,1,0,0);
        Toast.makeText(this, "1 clicked!", Toast.LENGTH_LONG).show();

    }

    tl.removeAllViewsInLayout();

    for(int i = 0; i < level; i++){
        TableRow new_tr = new TableRow(this);
        new_tr.setLayoutParams(layout_image);

        for(int j = 0; j< level; j++){
            new_tr.addView(image_array[i][j]);
        }
        tl.addView(new_tr);
    }

    tl.invalidate();

}

解决方案

If all you want to do is move the images around, you can just do setImageBitmap () operations on the existing ImageViews. You can use the same bitmaps and display them on whichever ImageViews you please.
