我正在尝试在a周围添加边距TextView,并编写了以下内容:
TextView t = (TextView)getLayoutInflater().inflate(R.layout.plaintexttable, null);
t.setText(new String(cp.decryptChar(words[i].charAt(l))+""));
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
params.setMargins(2,2,2,2);
t.setLayoutParams(params);
plainRow.addView(t);
运行代码时,我得到的LinearLayout.LayoutParams定义错误如下:
01-18 05:50:41.228: E/AndroidRuntime(1950): java.lang.NoSuchMethodError: android.widget.LinearLayout$LayoutParams.<init>
