Android中设置TextView的颜色setTextColor两种方法

package com.txlong; import android.app.Activity; import android.graphics.Color; import android.os.Bundle; import android.widget.TextView; public class ListViewDemoActivity extends Activity { // private ListView listView; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); TextView tv = new TextView(this); tv.setText("Test set TextView's color."); //方案一：通过ARGB值的方式 /** * set the TextView color as the 0~255's ARGB，These component values * should be [0..255], but there is no range check performed, so if they * are out of range, the returned color is undefined */ // tv.setTextColor(Color.rgb(255, 255, 255)); /** * set the TextView color as the #RRGGBB #AARRGGBB 'red', 'blue', * 'green', 'black', 'white', 'gray', 'cyan', 'magenta', 'yellow', * 'lightgray', 'darkgray' */ tv.setTextColor(Color.parseColor("FFFFFF")); /** 原来不知道有上边的方法，就用这个笨笨方法了 */ // String StrColor = null; // StrColor = "FFFFFFFF"; // int length = StrColor.length(); // if (length == 6) { // tv.setTextColor(Color.rgb( // Integer.valueOf(StrColor.substring(0, 2), 16), // Integer.valueOf(StrColor.substring(2, 4), 16), // Integer.valueOf(StrColor.substring(4, 6), 16))); // } else if (length == 8) { // tv.setTextColor(Color.argb( // Integer.valueOf(StrColor.substring(0, 2), 16), // Integer.valueOf(StrColor.substring(2, 4), 16), // Integer.valueOf(StrColor.substring(4, 6), 16), // Integer.valueOf(StrColor.substring(6, 8), 16))); // } //方案二：通过资源引用 // tv.setTextColor(getResources().getColor(R.color.my_color)); //方案三：通过资源文件写在String.xml中 // Resources resource = (Resources) getBaseContext().getResources(); // ColorStateList csl = (ColorStateList) resource.getColorStateList(R.color.my_color); // if (csl != null) { // tv.setTextColor(csl); // } //方案四：通过xml文件，如/res/text_color.xml // XmlPullParser xrp = getResources().getXml(R.color.text_color); // try { // ColorStateList csl = ColorStateList.createFromXml(getResources(), xrp); // tv.setTextColor(csl); // } catch (Exception e) { // } // listView = new ListView(this); // // Cursor cursor = getContentResolver().query( // Uri.parse("content://contacts/people"), null, null, null, null); // // startManagingCursor(cursor); // // ListAdapter listAdapter = new SimpleCursorAdapter(this, // android.R.layout.simple_expandable_list_item_2, cursor, // new String[] { "name", "name" }, new int[] { // android.R.id.text1, android.R.id.text2 }); // // listView.setAdapter(listAdapter); // setContentView(listView); setContentView(tv); } }
