Android GuideView实现首次登陆引导

 public class SimpleComponent implements Component {   @Override  public View getView(LayoutInflater inflater) {     LinearLayout ll = new LinearLayout(inflater.getContext());     LinearLayout.LayoutParams param =         new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);     ll.setOrientation(LinearLayout.VERTICAL);     ll.setLayoutParams(param);     TextView textView = new TextView(inflater.getContext());     textView.setText(R.string.welcome);     textView.setTextColor(inflater.getContext().getResources().getColor(R.color.color_white));     textView.setTextSize(20);     ImageView imageView = new ImageView(inflater.getContext());     imageView.setImageResource(R.mipmap.arrow);     ll.removeAllViews();     ll.addView(textView);     ll.addView(imageView);     ll.setOnClickListener(new View.OnClickListener() {       @Override       public void onClick(View view) {         Toast.makeText(view.getContext(), "引导层被点击了", Toast.LENGTH_SHORT).show();        }     });     return ll;  }     @Override    public int getAnchor() {       return Component.ANCHOR_BOTTOM;    }     @Override    public int getFitPosition() {       return Component.FIT_START;    }     @Override    public int getXOffset() {        return 30;    }     @Override    public int getYOffset() {       return 0;    }  }  public void showGuideView() {     final GuideBuilder builder1 = new GuideBuilder();   builder1.setTargetView(button1)       .setAlpha(150)       .setOverlayTarget(true)//设置目标区域是否高亮显示       .setOutsideTouchable(false);   builder1.setOnVisibilityChangedListener(new GuideBuilder.OnVisibilityChangedListener() {     @Override     public void onShown() {       // Toast.makeText(MutiGuideViewActivity.this, "show", Toast.LENGTH_SHORT).show();       }     @Override     public void onDismiss() {       button2.post(new Runnable() {         @Override         public void run() {           showGuideView2();         }       });       // Toast.makeText(MutiGuideViewActivity.this, "dismiss", Toast.LENGTH_SHORT).show();     }   });    builder1.addComponent(new SimpleComponent());   Guide guide = builder1.createGuide();   guide.setShouldCheckLocInWindow(false);   guide.show(MutiGuideViewActivity.this);}
