How to move image up and down continuously using translate animation in android? -

-

I have successfully used a side animation using the translation animation which implies that the image above Goes down. Here's the code: 

  Private Image View mScanner; Private Animation M Animation; Override public null on @reate (bundle saved instainstate) {super.naught (savedinstenstate); SetContentView (R.layout.main); MScanner = (ImageView) findViewById (R.id.Scanner); M animation = new translation animation (0, 0, 0, 500); MAnimation.setDuration (10000); MAnimation.setFillAfter (true); MAnimation.setRepeatCount (-1); MAnimation.setRepeatMode (Animation.REVERSE); MScanner.setAnimation (mAnimation); MScanner.setVisibility (View.VISIBLE); }   
 Now I want the image to reach the bottom of the screen, it should start returning to the top. How can I go about doing this?  
 Note: completed the reverse mode. Please see the code. But now the problem is that when it goes upwards from the bottom, it leaves leaves, how to remove these lines like an attached image? screenshot   
 
 
 Modify your code according to:  
  mScanner.setVisibility (see Visual.); MAnimation = new translation permission (translation permission. Abolt, 0f, translation invocation. Abosolute, 0f, translation permission .RELATIVE_TO_PARENT, 0f, translation permission .RELATIVE_TO_PARENT, 1.0f); MAnimation.setDuration (10000); MAnimation.setRepeatCount (-1); MAnimation.setRepeatMode (Animation.REVERSE); MAnimation.setInterpolator (New LinearInterpolator ()); MScanner.setAnimation (mAnimation);   
 And instead of using XML instead of the image please see the code below and place it on your  ImageView  src.  
  & lt ;? Xml version = "1.0" encoding = "UTF-8"? & Gt; & Lt; Size xmlns: Android = "http://schemas.android.com/apk/res/android" Android: Size = "Row" & gt; & Lt; Solid Android: Color = "# 0000ff" / & gt; & Lt; Size Android: width = "480dp" Android: height = "10dp" /> & Lt; Corners Android: Radius = "1dp" /> & Lt; Stroke Android: width = "3dp" Android: color = "# 000000" /> & Lt; / Size & gt;   
 I hope this will help you.

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
