无法在
中使用类型转换static String fontPath, temp, textColor;
static EditText text;
static TextView tv;
static Typeface tf;
案例1：
tv.setTextColor(Color.parseColor(textColor); // NOT WORKING
所以
使用无限的If else语句..比如..
if (textColor=="#FF0000")
tv.setTextColor(Color.parseColor("#FF0000")); // ROUGH SOLUTION
案例2：
同样在
text = (EditText) findViewById(R.id.et1);
temp = text.getText().toString();
text.setText(temp); // NOT WORKING -- BLANK TEXT
如果其他陈述不可能......
但
Toast.makeText(Opt.this, temp, Toast.LENGTH_SHORT).show();
这完美无缺......解决方案..？
编辑...... 1：
亲爱的 dmon
我想传递变量而不是固定值......
setText();
setTextColor();
setTypeface();
到TextView对象
＆安培;一个
setText();
到EditText对象......
尝试上面的代码无效..？

答案 0 :(得分：2)
你应该清理你的问题，根本不清楚你在问什么。我可以告诉你的是tv.setTextColor()没有Color对象（docs），它需要一个整数。你想要的是以下几点：
tv.setTextColor(0xFFFF0000);
或者，更好的是，只需将您想要的颜色放在resource file中并使用它
tv.setTextColor(getResources().getColor(R.color.red));
