以编程方式设置textview焦点颜色/更改主题中的焦点颜色

Question

1) Is it possible to set a TextView's color programmatically? If so what's the easiest way?

I want something else other that the default 4.0+ light-blue color.

I found and tried the following code without success:

StateListDrawable states = new StateListDrawable();
states.addState(new int[] {android.R.attr.state_pressed}, new ColorDrawable(0x1A000000));
states.addState(new int[] {android.R.attr.state_focused}, new ColorDrawable(0x1A000000));

if(android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.JELLY_BEAN) {
    tv.setBackgroundDrawable(states);
} else {
    tv.setBackground(states);
}

I do not wish any XML involved.

2) Can I change the focus color in my themes in general? If yes how?

XML is obviously fine here.

You can use ColorStateList , to specify the state color programmatically.

    int[][] states = new int[][] {
        new int[] { android.R.attr.state_pressed}, // pressed
        new int[] { android.R.attr.state_focused}, // focused
        new int[] { android.R.attr.state_enabled} // enabled
    };

    int[] colors = new int[] {
        Color.parseColor("#008000"), // green
        Color.parseColor("#0000FF"), // blue
        Color.parseColor("#FF0000")  // red
    };

    ColorStateList list = new ColorStateList(states, colors);
    textView.setTextColor(list);        
    textView.setClickable(true);
    textView.setFocusableInTouchMode(true);

使用http://android-holo-colors.com/生成仅使用特定颜色编辑文本的主题。

Answer 3

Create file res/drawable/text_color.xml:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_focused="true" android:state_pressed="false" android:color="#ffffff" />
    <item android:state_focused="true" android:state_pressed="true" android:color="#ffffff" />
    <item android:state_focused="false" android:state_pressed="true" android:color="#ffffff" />
    <item android:color="#000000" />
</selector>

Then use @drawable/text_color from xml (or R.drawable.text_color from code) as text color for your TextView.

Answer 4

Do you mean how to set color if some event happents? If it is then you can set textView color as follow:

  textView.setTextColor("give color-code"); 

Answer 5

You need to create style for that. By using style you can modify text color, background color, etc whatever you want.
