auto rotate android

In Android, we can rotate the Image Using Matrix post rotate.Example for Android image rotate :- 01 xmlversion="1.0"encoding="utf-8"?> 02 LinearLayoutandroid:id="@+id/LinearLayout01" 03 android:layout_width="fill_parent" 04 android:layout_height="fill_pa

1. First, let's talk about two classes: Matrixclass Overview The matrix class holds a 3x3 matrix for transforming coordinates. matrix does not have a constructor, so it must be explicitly initialized using either reset ()-to construct an identity matrix, or one of the set .. () functions (e.g. settranslate, setrotate,Etc .). The matrix class has a coordinate transformation matrix of 3x3. There is no constructor matrix, so it must be explicitly initialized to use or reset ()-How to Build a matri

Android Bitmap Related actionsSeveral common operations: zoom, crop, rotate, offsetMany operations require the matrix to support the matrix, which processes the bitmap and calculates the location of each pixel to display the bitmap.There is a 3x3 matrix in the matrix for image processing:mscale_x mskew_x mtrans_xmskew_y mscale_y mtrans_ympersp_0 mpersp_1 mpersp_2The specific purpose can be guessed accordi

This article mainly introduces how to use rotate to achieve the effect of continuous rotation of images in Android . Android platform provides two kinds of animation, one is Tween animation, that is, through the scene of the object constantly do image transformation (translation, scaling, rotation) to produce animation effect; the second type is Frame animation,

Type of animation Android animation is made up of four different types in XML Alpha Gradient Transparency Animation effect Scale Gradient Dimension Stretch animation effect Translate Move animation effect on picture transition position Rotate Picture Transfer rotation animation effect in javacode

[Android] custom arbitrary onDraw-based animation (not just PAN/rotate/zoom/alpha ),!,Ideas: 1. Time-based display ing. For example, if the degrees are specified, the arc is displayed, and the time sequence is added, the arc animation effect can be achieved. 2. specify the time sequence. One frame for animation Rendering Solution 1,Based on ObjectAnimator. During animation operation, the set function corre
