Android中的打字

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If-else语句。。像

if (textColor=="#FF0000") 
    tv.setTextColor(Color.parseColor("#FF0000")); // ROUGH SOLUTION

案例2：

也在

text = (EditText) findViewById(R.id.et1);
temp = text.getText().toString();

text.setText(temp); // NOT WORKING -- BLANK TEXT

如果其他语句不可能的话

但是

这个很好用。。。解决方案

编辑。。。。1:

亲爱的dmon

我要传递的变量不是固定值

setText();
setTextColor();
setTypeface();

文本视图对象

&一个

要编辑文本对象

尝试上述代码不起作用

你应该澄清你的问题，你问的根本不清楚。我可以告诉你的是，

tv.setTextColor（）

不接受

Color

对象（），它接受整数。您需要的是以下内容：

    tv.setTextColor(0xFFFF0000);

或者，更好的办法是，把你想要的颜色加上int a，然后使用它

    tv.setTextColor(getResources().getColor(R.color.red));

---

到底给出了什么错误？（粘贴错误）。你也可以发布更多的代码。需要更广泛的上下文..亲爱的Dmon，我想将变量not fixed value传递给setText（）；setTextColor（）；setTypeface（）；要查看TextView对象，请单击一个setText（）；要编辑文本对象。。。尝试上述代码无效。@PushkarHJoshi，请将其保存在一个非常简单的项目中，以不同的颜色大小和字体显示文本。。添加了完整的代码。。

    tv.setTextColor(0xFFFF0000);

    tv.setTextColor(getResources().getColor(R.color.red));
