我在这里通过此功能使用JSON创建自定义TextView（TextView正确显示）和ImageView，但ImageView未显示在相对布局中。帮我解决这个问题。 BubbleTextView是我的自定义ImageView，其StickerView属性
public RelativeLayout getViewByJson(final Context context, RelativeLayout viewGroup, String jsonArray) {
try {
JSONArray array = new JSONArray(jsonArray);
JSONObject jObjMain = array.getJSONObject(0);
JSONObject jObj = jObjMain.getJSONObject("canvas");
int canvasWidth = jObj.optInt("width");
int canvasHeight = jObj.optInt("height");
String canvasBackgroundPath = jObj.optString("background_path");
String canvasFramePath = jObj.optString("frame_path");
int canvasFilterAlpha = jObj.optInt("filter_alpha");
boolean canvasFilterEnabled = jObj.optBoolean("filter_enabled");
boolean canvasBackgroundBlured = jObj.optBoolean("background_blur");
JSONArray jsonArrayComponents = jObjMain.optJSONArray("components");
if (jsonArrayComponents.length() != 0 && jsonArrayComponents != null) {
for (int i = 0; i < jsonArrayComponents.length(); i++) {
JSONObject object = jsonArrayComponents.getJSONObject(i);
String componentType = object.getString("type");
if (componentType.equals("text_view")) {
int componentWidth = object.optInt("width");
int componentHeight = object.optInt("height");
int componentPositionX = object.optInt("position_x");
int componentPositionY = object.optInt("position_y");
int componentRotationAngle = object.optInt("rotation_angle");
int componentOpacity = object.optInt("opacity");
String componentViewState = object.optString("view_state");
String componentText = object.optString("text");

int componentStrokeWidth = object.optInt("stroke_width");
boolean componentUnderline = object.optBoolean("underline");
boolean componentStrikethrough = object.optBoolean("strike_thought");
boolean componentBold = object.optBoolean("bold");
//Custom TextView
StickerTextView stv = new StickerTextView(context);
stv.setText(componentText);
stv.setId(i);
stv.setTextViewWidth(componentWidth);
stv.setTextViewHeight(componentHeight);
stv.setTextSize(componentTextSize);
stv.setTextPosotion(componentPositionX, componentPositionY);
if (componentViewState.equals("false")) {
stv.setBorderVisiblity(false);
}
viewGroup.addView(stv);
final int finalI1 = i;
stv.setOperationListener(new StickerView.OperationListener() {
@Override
public void onClick() {

@Override

}
@Override

});
} else if (componentType.equals("image_view")) {

int componentColoreableColor = object.optInt("coloreable_color");
RelativeLayout.LayoutParams imageViewParam = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.MATCH_PARENT,
RelativeLayout.LayoutParams.MATCH_PARENT);
//Custom ImageView
BubbleTextView bubbleTextView = new BubbleTextView(context,
Color.BLACK, 0, "");
bubbleTextView.setLayoutParams(imageViewParam);
// bubbleTextView.
BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
int w = WIDTH_PX, h = HEIGHT_PX;
Bitmap.Config conf = Bitmap.Config.ARGB_8888;// see other conf types
Bitmap bmp = Bitmap.createBitmap(w, h, conf);// this creates a MUTABLE bitmap
Canvas canvasBlank = new Canvas(bmp);
Paint mPaint = new Paint();
int color = Color.argb(0, 0, 0, 0);
mPaint.setColor(color);
canvasBlank.drawRoundRect(new RectF(100, 100, 100, 100), 2, 2, mPaint);
bubbleTextView.setImageResource(R.drawable.apphub);
bubbleTextView.setBitmap(bmp);
if (componentViewState.equals("false")) {
bubbleTextView.setInEdit(false);
}
viewGroup.addView(bubbleTextView);
// viewGroup.bringChildToFront(bubbleTextView);
bubbleTextView.setOperationListener(new BubbleTextView.OperationListener() {
@Override
public void onDeleteClick() {
}
@Override
public void onEdit(BubbleTextView bubbleTextView) {
}
@Override
public void onClick(BubbleTextView bubbleTextView) {
}
@Override
public void onTop(BubbleTextView bubbleTextView) {
}
@Override
public void onChangeFont() {
}
});
}
}
}
} catch (JSONException e) {
e.printStackTrace();
Log.e("Exception JSON", e.getMessage());
}
return viewGroup;
}
我在View添加RelativeLayout：
RelativeLayout relativeLayout = new RelativeLayout(ImageSecondActivity.this);
RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(containerLayout.getWidth(), containerLayout.getHeight());
relativeLayout.setLayoutParams(layoutParams);
containerLayout.addView(renderViewByJSON.getViewByJson(ImageSecondActivity.this, relativeLayout, jsonString));
