很可能有一个重复的问题,但我还没有找到它。我正在做所有的事情,而不是使用xml。基本上我想要做的是在图像下面显示EditText。我正在使用带有ImageView和EditText的RelativeLayout。Android ImageView布局问题
这些是我设立了ImageView的和的EditText参数:
RelativeLayout.LayoutParams editTextParams = new RelativeLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
editTextParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
editTextParams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
editTextParams.width=500;
RelativeLayout.LayoutParams imageParams = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
imageParams.addRule(RelativeLayout.ALIGN_PARENT_TOP);
imageParams.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
imageParams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
imageParams.addRule(RelativeLayout.ABOVE, editText.getId());
我已经验证正确地放置在的EditText右下角和上面的图片。我碰到的是如果图片“太高”,那么它覆盖EditText。我也试过使用
imageView.setScaleType(ImageView.ScaleType.FIT_XY);
它也延伸到EditText。
,我使用完整的代码是这样的
RelativeLayout layout = (RelativeLayout) findViewById(R.id.mainLayout);
ImageView imageView = new ImageView(this);
EditText editText = new EditText(this);
RelativeLayout.LayoutParams editTextParams = new RelativeLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
editTextParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
editTextParams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
editTextParams.width=500;
RelativeLayout.LayoutParams imageParams = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
imageParams.addRule(RelativeLayout.ALIGN_PARENT_TOP);
imageParams.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
imageParams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
imageParams.addRule(RelativeLayout.ABOVE, editText.getId());
imageView.setLayoutParams(imageParams);
imageView.setScaleType(ImageView.ScaleType.FIT_XY);
editText.setLayoutParams(editTextParams);
Bitmap image = getImage();
imageView.setImageBitmap(image);
layout.addView(editText);
layout.addView(imageView);
感谢。任何建议将不胜感激。
500宽度是很多 – Murad
