我从网络服务中检索测验，我希望将其呈现为this，
我正在尝试以编程方式生成RadioButtons。
我有图片和文字测验，我使用rg.setOrientation();显示测验horizontaly / verticaly取决于quizz类型。
我尝试使用 Drawable 添加图片，但我无法将RadioButton置于图片下方居中。我只能得到this。 我无法将文本置于中心
我写的是代码。
final RadioGroup rg = (RadioGroup) v.findViewById(R.id.radio_group);
final int[] try_answer = {NUMBER_OF_TRY_MAX};
if (question.getImage()) {
if (!isTablet) {
rg.setOrientation(LinearLayout.VERTICAL);
} else {
rg.setOrientation(LinearLayout.HORIZONTAL);
}
rg.setGravity(Gravity.CENTER_HORIZONTAL);
for (int i = 0; i < answers.size(); i++) {
Answer answer = answers.get(i);
RadioButton button = new RadioButton(getContext());
db.open();
Image img = db.getImageWithURL(answer.getPicture());
db.close();
String localName = img.getImage();
String file = path + localName;
Bitmap bitmap = BitmapFactory.decodeFile(file);
Drawable d = new BitmapDrawable(getContext().getResources(), Bitmap.createScaledBitmap(bitmap, 300, 300, true));
d.setBounds(0, 0, 300, 300);
button.setCompoundDrawablesWithIntrinsicBounds(null,d,null,null);
button.setTextColor(Color.WHITE);
button.setTag(answer.right_answer);
button.setGravity(Gravity.LEFT);
button.setTextAlignment(View.TEXT_ALIGNMENT_CENTER);
button.setTextSize(TypedValue.COMPLEX_UNIT_SP, 18);
int[][] states = new int[][]{
new int[]{ android.R.attr.state_enabled}, // enabled
new int[]{-android.R.attr.state_enabled}, // disabled
new int[]{-android.R.attr.state_checked}, // unchecked
new int[]{ android.R.attr.state_checked}, // checked
new int[]{ android.R.attr.state_pressed} // pressed
};
int[] colors = new int[]{
Color.WHITE,
Color.GRAY,
Color.WHITE,
Color.BLUE,
Color.BLUE
};
ColorStateList myList = new ColorStateList(states, colors);
button.setButtonTintList(myList);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (try_answer[0] > 0) {
if ((Boolean) v.getTag()) {
displayRightAnswerImage(rg);
question.setAnswered(true);
checkIfAllQuestionsAnswered();
} else {
try_answer[0]--;
if (try_answer[0] == 0) {
displayRightAnswerImage(rg);
question.setAnswered(true);
checkIfAllQuestionsAnswered();
} else {
int selected = rg.getCheckedRadioButtonId();
RadioButton rb = (RadioButton) v.findViewById(selected);
Drawable[] drawables = rb.getCompoundDrawables();
Drawable draw = drawables[1];
draw.setAlpha(125);
Toast.makeText(getContext(), "il reste " + try_answer[0] + " essais", Toast.LENGTH_SHORT).show();
}
}
}
}
});
rg.addView(button);
}
} else {
rg.setOrientation(LinearLayout.VERTICAL);
for (int i = 0; i < answers.size(); i++) {
Answer answer = answers.get(i);
final RadioButton button = new RadioButton(getContext());
rg.addView(button);
button.setText(answer.getTitle());
button.setTextColor(Color.WHITE);
button.setTag(answer.right_answer);
button.setGravity(Gravity.CENTER_HORIZONTAL);
button.setTextSize(TypedValue.COMPLEX_UNIT_SP, 18);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (try_answer[0] > 0) {
if ((Boolean) v.getTag()) {
displayRightAnswer(rg);
question.setAnswered(true);
checkIfAllQuestionsAnswered();
} else {
try_answer[0]--;
if (try_answer[0] == 0) {
displayRightAnswer(rg);
question.setAnswered(true);
checkIfAllQuestionsAnswered();
} else {
Toast.makeText(getContext(), "il reste " + try_answer[0] + " essais", Toast.LENGTH_SHORT).show();
}
}
}
}
});
}
}
return v;
如何使显示看起来与第一个屏幕类似。
是否可以或应该使用除radiobutton之外的其他组件来正确渲染它？
