我有一个移动应用程序，允许人们通过文本或录音进行通信。该应用程序正在按我的意愿工作，但当一个人发送录音时问题就出现了。发送录音时我会检索它的网址代码，但我现在无法播放我想要做的是当message_type为＆＃34;录制＆＃34时，将我的视图从message_single_layout更改为audio_message_layout ;。这是我的代码。
public class MessageAdapter extends
RecyclerView.Adapter<MessageAdapter.MyMessageViewHolder>{
private ArrayList<Messages> arrayListMessages= new ArrayList<>();
private Context mcontext;
FirebaseAuth mAuth;
private DatabaseReference mUserDatabase;
private ViewGroup parent;
public ArrayAdapter adapter;
public MessageAdapter(Context context, ArrayList<Messages> arrayListMessages) {
this.arrayListMessages = arrayListMessages;
mcontext = context;
}
@Override
public MyMessageViewHolder onCreateViewHolder(ViewGroup parent, int viewType ) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.message_single_layout, parent,false);
return new MyMessageViewHolder(view);
}
@Override
public void onBindViewHolder(final MyMessageViewHolder holder, final int position) {
mAuth = FirebaseAuth.getInstance();
String mCurrentUser = mAuth.getCurrentUser().getUid();
final Messages messages = arrayListMessages.get(position);
String message_type = messages.getType();
String from_user = messages.getFrom();
mUserDatabase = FirebaseDatabase.getInstance().getReference().child("Users").child(from_user);
if(mCurrentUser.equals(messages.getFrom())){
holder.textViewMessage.setBackgroundResource(R.drawable.custom_message_bg_primary);
holder.textViewMessage.setTextIsSelectable(true);
holder.textViewMessage.setGravity(Gravity.RIGHT);
holder.textViewMessage.setTextColor(Color.WHITE);
holder.textViewMessage.setOnLongClickListener(new View.OnLongClickListener() {
@Override
public boolean onLongClick(View view)
{
CharSequence options[] = new CharSequence[]{"Delete", "Copy Text"};
final AlertDialog.Builder builder = new AlertDialog.Builder(mcontext);
builder.setTitle("Select Options");
builder.setItems(options, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
//Click Event for each item.
if (i == 0) {
String selectedItem = messages.getMessage();
arrayListMessages.remove(selectedItem);
Toast.makeText(mcontext, "Message deleted", Toast.LENGTH_SHORT).show();
}
if (i == 1)
{
ClipboardManager cm = (ClipboardManager) mcontext.getSystemService(Context.CLIPBOARD_SERVICE);
cm.setText(holder.textViewMessage.getText());
Toast.makeText(mcontext, "Copied to clipboard", Toast.LENGTH_SHORT).show();
}
}
});
builder.show();
return true;
}
});
}else{
holder.textViewMessage.setBackgroundResource(R.drawable.custom_message_bd_white);
holder.textViewMessage.setTextIsSelectable(true);
holder.textViewMessage.setGravity(Gravity.LEFT);
holder.textViewMessage.setTextColor(Color.BLACK);
holder.textViewMessage.setOnLongClickListener(new View.OnLongClickListener() {
@Override
public boolean onLongClick(View view) {
CharSequence options[] = new CharSequence[]{"Delete", "Copy Text"};
final AlertDialog.Builder builder = new AlertDialog.Builder(mcontext);
builder.setTitle("Select Options");
builder.setItems(options, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
//Click Event for each item.
if (i == 0) {
String selectedItem = messages.getMessage();
arrayListMessages.remove(selectedItem);
adapter.notifyDataSetChanged();
Toast.makeText(mcontext, "Message deleted", Toast.LENGTH_SHORT).show();
}
if (i == 1)
{
ClipboardManager cm = (ClipboardManager) mcontext.getSystemService(Context.CLIPBOARD_SERVICE);
cm.setText(holder.textViewMessage.getText());
Toast.makeText(mcontext, "Copied to clipboard", Toast.LENGTH_SHORT).show();
}
}
});
builder.show();
return true;
}
});
}
holder.textViewMessage.setText(messages.getMessage());
if(message_type.equals("text")) {
holder.textViewMessage.setText(messages.getMessage());
}
else if(message_type.equals("recording"))
{
//This is where i want to change my inflate from message_single_layout to audio_message_layout
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.audio_message_layout, parent,false);
return view;
}
}
@Override
public int getItemCount() {
return arrayListMessages.size();
}
class MyMessageViewHolder extends RecyclerView.ViewHolder{
TextView textViewMessage;
CircleImageView UserProfile;
public MyMessageViewHolder(View itemView) {
super(itemView);
textViewMessage = itemView.findViewById(R.id.messageTextView);
UserProfile = itemView.findViewById(R.id.message_profile_layout);
}
}
}
我想在message_type不是文本时更改我的适配器内容视图。我不知道如何继承audio_message_layout中的函数。提前谢谢。
