LineEditText类
public class LineEditText extends AppCompatEditText {
Rect mRect;
Paint mPaint;
public LineEditText(Context context, AttributeSet attrs) {
super(context, attrs);
mRect = new Rect();
mPaint = new Paint();
mPaint.setStyle(Paint.Style.STROKE);
mPaint.setStrokeWidth(2);
mPaint.setColor(0xFFFFD966);
}
@Override
protected void onDraw(Canvas canvas) {
int screenHeight = ((View)this.getParent()).getHeight();
int lineHeight = getLineHeight();
int numberOfLines = screenHeight / lineHeight;
Rect rect = new Rect();
Paint paint = new Paint();
int baseline = getLineBounds(0, rect);
for (int i = 0; i < numberOfLines; i++) {
canvas.drawLine(rect.left, baseline+1, rect.right, baseline+1, paint);
baseline += lineHeight;
}
super.onDraw(canvas);
}
}
备注适配器类
public class MemoAdapter extends RecyclerView.Adapter<MemoAdapter.MemoViewHolder> {
private ArrayList<Note> mNotes;
private OnNoteListener mListener;
public class MemoViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
TextView title, content, timestamp;
//TODO initialize rest of TextViews
public MemoViewHolder(@NonNull final View itemView) {
super(itemView);
this.title = (TextView) itemView.findViewById(R.id.title);
itemView.setOnClickListener(this);
}
@Override
public void onClick(View v) {
mListener.onMemoClick(getAdapterPosition());
}
}
public MemoAdapter(ArrayList<Note> notes, OnNoteListener listener) {
this.mNotes = notes;
this.mListener = listener;
}
@NonNull
@Override
public MemoViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.activity_memo_content, parent, false);
return new MemoViewHolder(view);
}
@Override
public void onBindViewHolder(@NonNull MemoViewHolder holder, int position) {
holder.title.setText(mNotes.get(position).getTitle());
}
@Override
public int getItemCount() {
return mNotes.size();
}
public interface OnNoteListener{
void onMemoClick(int position);
}
}
这有什么问题吗？关于EditText自定义类吗？请给我任何线索。
第12行是指我的xml文件，实际上是LineEditText
android.view.InflateException: Binary XML file line #12 in com.example.memos:layout/activity_memo_content: Binary XML file line #12 in com.example.memos:layout/activity_memo_content: Error inflating class LineEditText
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
最佳答案
造成原因：java.lang.ClassNotFoundException：android.view.LineEditText
它在LineEditText包内搜索android.view，因为它是SDK的一部分，所以不是放置它的地方。
检查LineEditText的位置，并将xml中的android.view替换为具有LineEditText的软件包。
