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());
}
