TextView超过n行显示…

直接上代码

public static void truncate(final TextView view, final int maxLine) {
	        ViewTreeObserver vto = view.getViewTreeObserver();
	        vto.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
	            public void onGlobalLayout() {
	                if (view.getLineCount() > maxLine) {
	                    int lineEndIndex = view.getLayout().getLineEnd(maxLine - 1);
	                    String text = view.getText().subSequence(0,
	                            lineEndIndex - 3)
	                            + "...";
	                    view.setText(text);
	                }
	            }
	        });
	    }
