android - 安卓那不好吗？是个错误？ margin

通过将页边距设置为零，图像将填满整个屏幕。但是要将边距设置为一百，除右边之外，它都适合。为什么呢

ImageView imagen = new ImageView(this);
RelativeLayout relative = new RelativeLayout(this);
RelativeLayout.LayoutParams labelLayoutParams = new RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
relative.setLayoutParams(labelLayoutParams);
RelativeLayout rl = new RelativeLayout(this);
RelativeLayout.LayoutParams layoutImagenClicker = new RelativeLayout.LayoutParams
(RelativeLayout.LayoutParams.FILL_PARENT, RelativeLayout.LayoutParams.FILL_PARENT);
layoutImagenClicker.setMargins(0, 0, 0, 0);
imagen.setBackgroundResource(R.drawable.barra_seek_bar);
imagen.setLayoutParams(layoutImagenClicker);
rl.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
rl.addView(imagen);
relative.addView(rl);
setContentView(relative);

ImageView imagen = new ImageView(this);
RelativeLayout relative = new RelativeLayout(this);
RelativeLayout.LayoutParams labelLayoutParams = new RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
relative.setLayoutParams(labelLayoutParams);
RelativeLayout rl = new RelativeLayout(this);
RelativeLayout.LayoutParams layoutImagenClicker = new RelativeLayout.LayoutParams
(RelativeLayout.LayoutParams.FILL_PARENT, RelativeLayout.LayoutParams.FILL_PARENT);
layoutImagenClicker.setMargins(100, 100, 100, 100);
imagen.setBackgroundResource(R.drawable.barra_seek_bar);
imagen.setLayoutParams(layoutImagenClicker);
rl.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
rl.addView(imagen);
relative.addView(rl);
setContentView(relative);

具有相同填充的不同边距？

layoutImagenClicker.setMargins(0, 0, 0, 0);
layoutImagenClicker.setMargins(100, 100, 100, 100);

看这个！

layoutImagenClicker.setMargins(100, 100, 200, 100);

相同的结果集保证金正确为100或200。这是一个错误吗？

最佳答案

尝试在RelativeLayout包装器上设置填充，然后删除imageview上的边距。至于您最初的问题，我不知道为什么会搞砸，但是我总是更喜欢从边距转移到填充...

ImageView imagen = new ImageView(this);
RelativeLayout relative = new RelativeLayout(this);
RelativeLayout.LayoutParams labelLayoutParams = new RelativeLayout.LayoutParams
        (LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);

// Padding on the RelativeLayout
relative.setPadding(100,100,100,100);

relative.setLayoutParams(labelLayoutParams);
RelativeLayout rl = new RelativeLayout(this);
RelativeLayout.LayoutParams layoutImagenClicker = new RelativeLayout.LayoutParams
         (RelativeLayout.LayoutParams.FILL_PARENT, RelativeLayout.LayoutParams.FILL_PARENT);

// Remove the margin on the child
//layoutImagenClicker.setMargins(100, 100, 100, 100);


imagen.setBackgroundResource(R.drawable.barra_seek_bar);
imagen.setLayoutParams(layoutImagenClicker);
rl.setLayoutParams(new LayoutParams    (LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
rl.addView(imagen);
relative.addView(rl);
setContentView(relative);

祝好运
