具有OVAL形状的GradientDrawable在以编程方式添加的Text View中无法正常工作

activity_main.xml <LinearLayout android:id="@+id/lv" android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="horizontal"/> MainActivity.java 1-查找linearlayout的ID 2-然后使用TextView或Button等创建动态视图... private void createDynamicView() { TextView tvDigit = new TextView(this); tvDigit.setText("1"); tvDigit.setTextColor(ContextCompat.getColor(this, R.color.white)); tvDigit.setGravity(Gravity.CENTER); tvDigit.setTextSize(18); customViewOval(tvDigit, ContextCompat.getColor(this, R.color.teal_500), ContextCompat.getColor(this, R.color.transparant), 100, 100); TextView tvName = new TextView(this); tvName.setText("Richard"); tvName.setGravity(Gravity.CENTER); tvName.setTextColor(ContextCompat.getColor(this, R.color.black_80)); tvName.setPadding(10, 0, 0, 0); tvName.setTextSize(18); lv.addView(tvDigit); lv.addView(tvName); customViewWithRadius(lv, ContextCompat.getColor(this, R.color.lightgrey), ContextCompat.getColor(this, R.color.transparant), 90);} 椭圆形内数字的自定义视图 public static void customViewOval(View view, int backgroundColor, int borderColor, int height, int width) { GradientDrawable shape = new GradientDrawable(); shape.setShape(GradientDrawable.OVAL); shape.setColor(backgroundColor); shape.setStroke(1, borderColor); LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(height, width); view.setLayoutParams(layoutParams); view.setBackgroundDrawable(shape);} 具有半径的主要背景的自定义视图 private static void customViewWithRadius(View view, int backgroundColor, int borderColor, float radius) { GradientDrawable shape = new GradientDrawable(); shape.setShape(GradientDrawable.RECTANGLE); shape.setCornerRadii(new float[]{radius, radius, radius, radius, radius, radius, radius, radius}); shape.setColor(backgroundColor); shape.setStroke(1, borderColor); LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT); view.setLayoutParams(layoutParams); view.setPadding(10, 10, 40, 10); view.setBackgroundDrawable(shape);}希望这将有助于解决您的问题.I have programmatically added Text View and Button. Codefinal TextView test = new TextView(getApplicationContext());test.setText(String.valueOf(counterQuantity));test.setTextColor(getResources().getColor(R.color.black));test.setTextSize(TypedValue.COMPLEX_UNIT_DIP, 10);GradientDrawable border = new GradientDrawable();border.setShape(GradientDrawable.OVAL);border.setStroke(1, getResources().getColor(R.color.black));border.setCornerRadius(2);border.setColor(getResources().getColor(R.color.colorPrimaryDark)); //white backgroundif (Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN) { test.setBackgroundDrawable(border);} else { test.setBackground(border);}Button articleButtonId = (Button) v;int articleButton = articleButtonId.getId();final String articleButtonText = articleButtonId.getText().toString();Log.w("articleButton", "" + articleButton);final Button button = new Button(getApplicationContext());button.setText(test.getText() + " " + " " + articleButtonText);button.setGravity(Gravity.CENTER);button.setTextSize(TypedValue.COMPLEX_UNIT_DIP, 12);button.setTextColor(getResources().getColor(R.color.black));button.setBackgroundColor(getResources().getColor(R.color.article_button_group));button.setBackground(getResources().getDrawable(R.drawable.order_button_group_bg));Here in above code i have a Text View and Button added programatically.The text of Text Views added inside Button setText method using concatination.Now i want to make only Text View in Circle View.I have tried with GradientDrawable but the effect on Text View is remains same no any effects taken by Text View.In other scenarios GradientDrawable is working fine but in this scenario is not getting what i want.Here is image what i want exactly.Any help will be highly appreciated. 解决方案 below is a snippet for your problem and I've tested on kitkat and marshmallow devices, it is showing properly, So give it a try...activity_main.xml<LinearLayout android:id="@+id/lv" android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="horizontal"/>MainActivity.java1- find id of linearlayout2 - Then create dynamic view with TextView or Button etc...private void createDynamicView() { TextView tvDigit = new TextView(this); tvDigit.setText("1"); tvDigit.setTextColor(ContextCompat.getColor(this, R.color.white)); tvDigit.setGravity(Gravity.CENTER); tvDigit.setTextSize(18); customViewOval(tvDigit, ContextCompat.getColor(this, R.color.teal_500), ContextCompat.getColor(this, R.color.transparant), 100, 100); TextView tvName = new TextView(this); tvName.setText("Richard"); tvName.setGravity(Gravity.CENTER); tvName.setTextColor(ContextCompat.getColor(this, R.color.black_80)); tvName.setPadding(10, 0, 0, 0); tvName.setTextSize(18); lv.addView(tvDigit); lv.addView(tvName); customViewWithRadius(lv, ContextCompat.getColor(this, R.color.lightgrey), ContextCompat.getColor(this, R.color.transparant), 90);}custom view for digit within ovalpublic static void customViewOval(View view, int backgroundColor, int borderColor, int height, int width) { GradientDrawable shape = new GradientDrawable(); shape.setShape(GradientDrawable.OVAL); shape.setColor(backgroundColor); shape.setStroke(1, borderColor); LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(height, width); view.setLayoutParams(layoutParams); view.setBackgroundDrawable(shape);}custom view for main background with radiusprivate static void customViewWithRadius(View view, int backgroundColor, int borderColor, float radius) { GradientDrawable shape = new GradientDrawable(); shape.setShape(GradientDrawable.RECTANGLE); shape.setCornerRadii(new float[]{radius, radius, radius, radius, radius, radius, radius, radius}); shape.setColor(backgroundColor); shape.setStroke(1, borderColor); LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT); view.setLayoutParams(layoutParams); view.setPadding(10, 10, 40, 10); view.setBackgroundDrawable(shape);}Hope it'll help to solve your problem. 这篇关于具有OVAL形状的GradientDrawable在以编程方式添加的Text View中无法正常工作的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
