自定义主题

   android中如何自定义主题，如下图：


   如何将主题进行改变呢？在android中他为我们提供了Window中setFeatureInt，可以让我们自定义各种各样的桌面样式。

  requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
                setContentView(R.layout.custom_title);
                getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.custom_title_1);

   requestWindwoFeature是判断该特征在当前是否存在（显示），如果改特征没有显示就让他显示，setFeatureInt方法为指定的窗口特征设置值（该界面特征的布局）。关于更多的Window类的介绍可以参考网站：http://www.cnblogs.com/GnagWang/archive/2011/03/31/2001067.html
   代码：

protected void onCreate(Bundle savedInstanceState) {
                super.onCreate(savedInstanceState);

             /**
                * 自定义主题
                */
                requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
                setContentView(R.layout.custom_title);
                getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.custom_title_1);
                /**
                 * id为left_text.right_text为自定义布局文件内容
                 */
                final TextView leftText = (TextView) findViewById(R.id.left_text);
                final TextView rightText = (TextView) findViewById(R.id.right_text);
                final EditText leftTextEdit = (EditText) findViewById(R.id.left_text_edit);
                final EditText rightTextEdit = (EditText) findViewById(R.id.right_text_edit);
                /**
                 * 设置button监听事件，一边随时改变左右主题的内容
                 */
                Button leftButton = (Button) findViewById(R.id.left_text_button);
                Button rightButton = (Button) findViewById(R.id.right_text_button);
                
                leftButton.setOnClickListener(new OnClickListener() {
                        public void onClick(View v) {
                                leftText.setText(leftTextEdit.getText());
                        }
                });
                rightButton.setOnClickListener(new OnClickListener() {
                        public void onClick(View v) {
                                rightText.setText(rightTextEdit.getText());
                        }
