The following simply describes a method for the debugging of android.

In the android app development and debugging process, often you need to use to fight Log ways to view the function call site.

Here are a way to print the current function call stack relations

    	StackTraceElement[] ste = new Throwable().getStackTrace();	
    	if(ste.length >=1)
    	{
    		for(int i = 1; i < ste.length; i++)
    		{
    			Log.d(TAG, "File:" + ste[i].getFileName() + ", Line: " + ste[i].getLineNumber() + ", MethodName:" + ste[i].getMethodName());
    		}
    	}

Here I in the above-described block functions LabelDisplayItem updateContent class, printed below Log

D/AlbumSetDir( 1554): File:AlbumSetSlidingWindow.java Line: 550 MethodName:render
D/AlbumSetDir( 1554): File:SlotView.java Line: 375 MethodName:renderItem
D/AlbumSetDir( 1554): File:SlotView.java Line: 304 MethodName:render
D/AlbumSetDir( 1554): File:AlbumSetView.java   Line: 203 MethodName:render
D/AlbumSetDir( 1554): File:GLView.java Line: 244 MethodName:renderChild
D/AlbumSetDir( 1554): File:GLView.java Line: 218 MethodName:render
D/AlbumSetDir( 1554): File:AlbumSetPage.java   Line: 175 MethodName:render
D/AlbumSetDir( 1554): File:GLRootView.java Line: 305 MethodName:onDrawFrameLocked
D/AlbumSetDir( 1554): File:GLRootView.java Line: 266 MethodName:onDrawFrame
D/AlbumSetDir( 1554): File:GLSurfaceView.java   Line: 1468 MethodName:guardedRun
D/AlbumSetDir( 1554): File:GLSurfaceView.java   Line: 1222 MethodName:run

Note that this is the stack, call the relationship is to look from the bottom up

If you just want to add some output in a file, for example, you want to output current which line, in which file, use the following test code on it

public class Test  
{  
    public static void main(String args[])  
    {  
        System.out.println("This is " + getLineInfo());  
    }  
   
    public static String getLineInfo()  
    {  
        StackTraceElement ste = new Throwable().getStackTrace()[1];  
        return ste.getFileName() + ": Line " + ste.getLineNumber();  
    }  
} 


打印函数调用栈的方法：Log.d(TAG,Log.getStackTraceString(new Throwable()));
