Question

我想使用列表

中的onItemClickListener将片段的布局替换为片段

@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
    switch (position) {
        case 0:
            intent = new Intent(this, Answer.class);
            startActivity(intent);
            Answer_0 answer_0=new Answer_0();
            android.app.FragmentManager fragmentManager=getFragmentManager();
            android.app.FragmentTransaction fragmentTransaction=fragmentManager.beginTransaction();
            fragmentTransaction.replace(R.id.fragment_show,answer_0);
            fragmentTransaction.commit();
            break;

当我点击项目时，应用程序会显示ANR并关闭。

将此功能添加到您的活动

public void openFragment(Fragment fragment) {

            android.support.v4.app.FragmentManager fragmentManager = getSupportFragmentManager();
            fragmentManager.beginTransaction().replace(R.id.container, fragment).commit();

        }

并像这样使用

@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
    switch (position) {
        case 0:
            openFragment(new yourFragment1());
            break;

            case 1:
            openFragment(new yourFragment2());
            break;

            case 2:
            openFragment(new yourFragment3());
            break;
        }

并确保导入android.support.v4而不是android.app

在你开启活动后这样做

如果您想在活动开始时加载片段，请将openFragment(new yourFragment())放在该活动的onCreate方法上

android片段使用活动
