解决方案

当你使用 android.support.v4.app.DialogFragment ，你应该传递给显示（） android.support.v4.app.FragmentManager 可查询的使用<$ C $实例C> getSupportFragmentManager（）通话。希望这有助于。

I am getting an error "The method show(FragmentManager, String) in the type DialogFragment is not applicable for the arguments (FragmentManager, String)" Please anyone help me.

package com.example.test1;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.support.v4.app.DialogFragment;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentActivity;

public class MainActivity extends Activity {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}

public void click(View view) {
        DialogFragment newFragment = new FireMissilesDialogFragment();
        newFragment.show(getFragmentManager(), "missiles");
}

public boolean onCreateOtionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.activity_main, menu);
    return true;
}
}

解决方案

As you're using android.support.v4.app.DialogFragment, you should pass to show() an instance of android.support.v4.app.FragmentManager which can be queried using an getSupportFragmentManager() call. Hope this helps.
