我有一個Sudoku網格圖像加載到我的應用程序中,但我遇到很多麻煩讓EditTexts出現在每個方塊中。當我運行該應用程序時,EditTexts中的數字幾乎不可見。我試過改變背景顏色和文字顏色,沒有任何改變。以編程方式創建基於數獨網格的EditTexts
/* PROGRAMATICALLY ADD EDITVIEWS via waiting for draw */
layout.getViewTreeObserver().addOnGlobalLayoutListener(
new ViewTreeObserver.OnGlobalLayoutListener()
{
public void onGlobalLayout()
{
layout.getViewTreeObserver().removeOnGlobalLayoutListener(this);
/* not used yet
int height = grid.getMeasuredHeight();
int width = grid.getMeasuredWidth();
int top = grid.getTop();
//int bottom = grid.getBottom();
int left = grid.getLeft();
int square_height = height/9;
int square_width = width/9;*/
for (int r = 0; r < 9; r++)
{
for (int c = 0; c < 9; c++)
{
text_boxes[r][c] = new EditText(getApplicationContext());
text_boxes[r][c].setId(r+c);
text_boxes[r][c].setText("1");
text_boxes[r][c].setInputType(InputType.TYPE_CLASS_NUMBER);
text_boxes[r][c].setFilters(new InputFilter[] {new InputFilter.LengthFilter(1)});
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
params.setMargins(c*10, r*50, 0, 0);
layout.addView(text_boxes[r][c], params);
text_boxes[r][c].setBackgroundColor(0x0FF00);
}
}
}
});
