重新加载片段，Edittext的文本未清除 [英] Reloading fragment, Edittext's text not cleared

问题描述

在我的片段中有很多微调器和编辑文本，提交按钮用于保存数据，重设按钮用于重设所有元素(编辑文本和微调器).我已经使用以下代码重设所有控件

In my fragment there are lot of spinner and edit text and submit button is to save data, reset button is to reset all elements(Edit Texts and Spinners). I have used folllowing code to reset all controls

FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.detach(this).attach(this).commit();

，但不会清除editext.所有微调器都已重置，但editext的文本保持不变

but it doesn't clear editext. All spinners are reset but editext's text remain as it is

推荐答案

尝试以下方法:

 FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
 ft.remove(this).replace(R.id.container, YourFragment.newInstance());;
 ft.commit();

性能说明:如果仅替换片段只是为了重置值，那么最好手动重置值，因为与手动重置值相比，替换整个片段会涉及很多额外的开销.

Performance note : if you are only replacing the fragment just to reset the values then its better to reset the values manually because replacing the entire fragment involves lot of extra overhead as compared to manually resetting values.
