Unable to Use Typecasting in 

static String fontPath, temp, textColor;
static EditText text;
static TextView tv;
static Typeface tf;

Case 1:

tv.setTextColor(Color.parseColor(textColor); // NOT WORKING

so

Using infinite If else statements .. like ..

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

Case 2:

Also in 

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

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

Where if else statements are impossible ..

but

Toast.makeText(Opt.this, temp, Toast.LENGTH_SHORT).show();

This works perfectly ... Solution.. ?

EDIT.... 1:

Dear dmon

I want to pass variable not a fixed value ...

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

to TextView Object

& One

setText();

to EditText Object ...

tried above code not working ..?

Complete code ...

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()它不需要一个Color对象（docs），它需要一个整数。你想要的是以下内容：

    tv.setTextColor(0xFFFF0000);

或者，更好的是，只需将您想要的颜色放入资源文件并使用它

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