我有一个片段,我需要在其中显示自定义对话框.
请查看下面的代码.
- public class MyFragment extends Fragment{
- @Override
- public void onCreate(Bundle savedInstanceState) {
- super.onCreate(savedInstanceState);
- }
- @Override
- public View onCreateView(LayoutInflater inflater,ViewGroup container,Bundle savedInstanceState) {
- View rootView = inflater.inflate(R.layout.send_layout,container,false);
- TextView txtView = (TextView) rootView.findViewById(R.id.tv);
- txtView.setOnClickListener(new View.OnClickListener() {
- @Override
- public void onClick(View v) {
- openDialog();
- }
- });
- return rootView;
- }
- public void openDialog(){
- AppCompatDialog dialog = new AppCompatDialog(getContext(),R.style.package_types__dialog);
- dialog.setContentView(R.layout.package_types_dialog);
- dialog.show();
- }
- }
删除行时：
- dialog.setContentView(R.layout.package_types_dialog);
- FATAL EXCEPTION: main

解决方法
我已经为你的情况实施并尝试了很多替代方案,它的工作非常好,所以我没有机会审查你的错误.但我可以建议你用AlertDialog.Builder替换AppCompatDialog,这是一个android.support.v7.app类.
替换此代码
- public void openDialog(){
- AppCompatDialog dialog = new AppCompatDialog(getContext(),R.style.package_types__dialog);
- dialog.setContentView(R.layout.package_types_dialog);
- dialog.show();
- }
同
- public void openDialog(){
- AlertDialog.Builder dialog = new AlertDialog.Builder(getContext(),R.style.package_types__dialog);
- dialog.setView(R.layout.package_types_dialog);
- }
注意 ：
如果您有任何处理对话事件的类,则扩展android.support.v4.app.DialogFragment的DialogFragment.并且不要忘记覆盖onCreateDialog方法.完整的课程看起来像这样
- import android.os.Bundle;
- import android.support.v4.app.DialogFragment;
- /**
- * Created by Shreekrishna on 2/29/2016.
- */
- public class PackageTypesDialog extends DialogFragment {
- @Override
- public Dialog onCreateDialog(Bundle savedInstanceState) {
- return super.onCreateDialog(savedInstanceState);
- }
- }
这可能会解决您的问题！
