Question

android 在fragment里面怎么使用dialogfragment

Answer 1

使用Fragment的Activity
MainActivity类要继承FragmentActivity，因为在下面getSupportFragmentManager要用到

public class MainActivity extends FragmentActivity {

public Button btn_search;
Fragment_Search dialogFragment;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

btn_search = (Button) findViewById(R.id.btn_search);
btn_search.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View arg0) {
showSearchDialog();
}
});
}

protected void showSearchDialog() {

// Create and show the dialog.
if(dialogFragment == null)
dialogFragment = new Fragment_Search();
dialogFragment.setStyle(DialogFragment.STYLE_NO_TITLE, 0);
dialogFragment.show(getSupportFragmentManager(), "dialog");
}

}
