问题描述
我想在画布上的水龙头上放置编辑文本. 我想从用户那里获取输入并将该编辑文本设置为画布.
i want to place edit text on tap on canvas. i want to take input from user and set that edit text to canvas.
这是我的代码:
@Override
protected void onDraw(Canvas canvas) {
for (Point point : points) {
LinearLayout lL = new LinearLayout(getContext());
EditText editTextView = new EditText(getContext());
editTextView.setFocusableInTouchMode(true);
editTextView.setFocusable(false);
editTextView.setClickable(true);
editTextView.setText("sadsdadadadadsadasds");
editTextView.setVisibility(View.VISIBLE);
lL.addView(editTextView);
lL.setDrawingCacheEnabled(true);
lL.measure(canvas.getWidth(), canvas.getHeight());
lL.layout(0, 0, canvas.getWidth(), canvas.getHeight());
canvas.drawBitmap(lL.getDrawingCache(), point.x, point.y, mPaint);
// canvas.drawText("(0,0)", point.x, point.y, mPaint);
// Log.d(TAG, "Painting: "+point);
}
}
@Override
public boolean onTouch(View v, MotionEvent event) {
float x = event.getX();
float y = event.getY();
InputMethodManager inputMethodManager;
TextView tv1=new TextView(getContext());
LinearLayout lL = new LinearLayout(getContext());
// return super.onTouchEvent(event);
Point point = new Point();
point.x = (int) event.getX();
point.y = (int) event.getY();
points.add(point);
invalidate();
return true;
}
错误:
问题是EditText被放置在Canvas上但不能单击
PROBLEM is that EditText is Getting placed on Canvas but not clickble
推荐答案
首先不要将其绘制在画布上,因为触摸仅应用于该画布,因此在Activity/xml中绘制编辑文本和自定义视图(画布),如果仍然无法点击,请尝试将编辑文字放在最前面
First dont draw it on canvas, as touches are applied only to that canvas, in your Activity/xml draw the edit text and your custom view (canvas), if still not clickable try to bring edit text to front
yourLayout.bringChildToFront(yourEditText);
您的xml是这样的
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- your custom view here -->
<!-- edittext here -->
<EditText
android:id="@+id/settings_text_y"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</RelativeLayout>
