android 功能引导界面实现

一.界面实现：

      借鉴了别人的实例，然后记录下引导界面的实现，总体来说实现不算困难，前提是要有个美工帮你做这些引导图片（找了张图片凑合用吧）：

   主界面：

public class MainActivity extends PromptActivity {
    //activity的生命周期
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		
		setGuideResId(R.drawable.prompt2);// 添加引导页
	}
}

public class PromptActivity extends Activity {

	private int guideResourceId = 0;// 引导页图片资源id
	private PromptSharedPreferences psp;
	@Override
	protected void onStart() {
		super.onStart();
		addGuideImage();// 添加引导页
	}

	//显示引导图片
	public void addGuideImage() {
		psp = new PromptSharedPreferences();
		View view = getWindow().getDecorView().findViewById(
				R.id.my_content_view);// 查找通过setContentView上的根布局
		if (view == null)
			return;
		if (psp.takeSharedPreferences(this)) {
			// 有过功能引导，就跳出
			return;
		}
		ViewParent viewParent = view.getParent();
		if (viewParent instanceof FrameLayout) {
			final FrameLayout frameLayout = (FrameLayout) viewParent;
			if (guideResourceId != 0) {
				// 设置了引导图片
				final ImageView guideImage = new ImageView(this);
				FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(
						ViewGroup.LayoutParams.FILL_PARENT,
						ViewGroup.LayoutParams.FILL_PARENT);
				guideImage.setLayoutParams(params);
				guideImage.setScaleType(ScaleType.FIT_XY);
				guideImage.setImageResource(guideResourceId);
				guideImage.setOnClickListener(new View.OnClickListener() {
					@Override
					public void onClick(View v) {
						//删除引导图片
						frameLayout.removeView(guideImage);
						//保存记录
						psp.saveSharedPreferences(PromptActivity.this, "启动了");
					}
				});
				
				frameLayout.addView(guideImage);// 添加引导图片

			}
		}
	}
	//获得图片id
	protected void setGuideResId(int resId) {
		this.guideResourceId = resId;
	}

}
