今天看到同事使用的是我没见过的DialogFragment这个控件, 比以往看到的都挺好用.
使用方法如下:
FragmentManager fragmentManager = getSupportFragmentManager();
RegisterDialogFragment signDialogFragment = RegisterDialogFragment.newInstance(appDesc);
signDialogFragment.setOnConfirmListener(new RegisterDialogFragment.OnConfirmListener() {
@Override
public void onConfirm() {
downloadBinder.startDownload(url);
}
});
signDialogFragment.show(fragmentManager, "RegisterDialogFragment");
import android.app.Dialog;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v7.app.AppCompatDialog;
import android.support.v7.app.AppCompatDialogFragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;
import com.jt.base.R;
/**
* A simple {@link Fragment} subclass.
*/
public class RegisterDialogFragment extends AppCompatDialogFragment {
public RegisterDialogFragment() {
// Required empty public constructor
}
private String content;
public static RegisterDialogFragment newInstance(String type) {
RegisterDialogFragment registerDialogFragment = new RegisterDialogFragment();
Bundle bundle = new Bundle();
bundle.putString("type", type);
registerDialogFragment.setArguments(bundle);
return registerDialogFragment;
}
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
View contentView = LayoutInflater.from(getActivity()).inflate(R.layout.fragment_register_dialog, null);
if (getArguments() != null) {
content = getArguments().getString("type");
}
initView(contentView);
AppCompatDialog appCompatDialog = new AppCompatDialog(getContext(), R.style.DialogNoTitle);
appCompatDialog.setContentView(contentView, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT));
appCompatDialog.setCanceledOnTouchOutside(false);
return appCompatDialog;
}
private void initView(View view) {
ImageView image = (ImageView) view.findViewById(R.id.dialog_btn);
TextView text = (TextView) view.findViewById(R.id.dialog_text);
text.setText(content);
image.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
getDialog().dismiss();
if (onConfirmListener != null) {
onConfirmListener.onConfirm();
}
}
});
view.findViewById(R.id.dialog_close).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
getDialog().dismiss();
}
});
}
private OnConfirmListener onConfirmListener;
public void setOnConfirmListener(OnConfirmListener onConfirmListener) {
this.onConfirmListener = onConfirmListener;
}
public interface OnConfirmListener {
void onConfirm();
}
}
然后我觉得这个也写得很好的:
