从活动中删除片段 [英] Removing fragments from an activity

问题描述

FragmantClass rSum = new FragmantClass();
getSupportFragmentManager().beginTransaction().remove(rSum).commit();       

当我加载切换另一个片段时，我正在尝试删除此片段.上面的片段不会被删除.这是我调用的切换片段的方法.

I am trying to remove this fragment, when i load switch another fragment. The above fragment does not get removed. Here is the method i am calling to switch fragments.

public void switchContent(Fragment fragment) {
    FragmantClass rSum = new FragmantClass();
    getSupportFragmentManager().beginTransaction().remove(rSum).commit();
    mContent = fragment;
    getSupportFragmentManager()
        .beginTransaction()
        .replace(R.id.content_frame, fragment)
        .commit();
    getSlidingMenu().showContent();
}

推荐答案

getSupportFragmentManager().beginTransaction().
remove(getSupportFragmentManager().findFragmentById(R.id.frame)).commit();

尝试一下，它应该可以工作.

Try this, it should work.

public void switchContent(Fragment fragment) {
    getSupportFragmentManager().beginTransaction().
    remove(getSupportFragmentManager().findFragmentById(R.id.frame)).commit();
    mContent = fragment;
    getSupportFragmentManager()
        .beginTransaction()
        .replace(R.id.content_frame, fragment)
        .commit();
    getSlidingMenu().showContent();
}
