我使用camera2和im在縮略圖中長按後顯示我的照片/視頻預覽。此外，根據相機在拍攝照片時的方向進行旋轉。例如，如果我在90º拍攝了一張照片，我的預覽也會旋轉90º。在紋理視圖中旋轉視頻/媒體播放器
一切工作正常，即時通訊使用customContainer和即時通訊使用onLayout和OnMeasure創建我的預覽取決於屏幕的大小，縱橫比和方向。它適用於照片。當我嘗試對視頻執行相同操作時，出現問題，它們只能在0º下工作。
我試着旋轉包含我的MediaPlayer的TextureView，但在此之後，我的onLayout變得瘋狂，並且找不到（l，t，r，b）組合來正確測量它。
這裏是我的XML：
<?xml version="1.0" encoding="utf-8"?>
<com.android.camera.ui.common.ThumbnailContainer xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/preview_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/rounded_rectangle_thumbnail_preview"
android:visibility="invisible">
<TextureView
android:id="@+id/show_video_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:visibility="invisible"/>
<ImageView
android:id="@+id/image_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:adjustViewBounds="true"
android:visibility="invisible"
/>
</com.android.camera.ui.common.ThumbnailContainer>
這裏是我的表面代碼：
@Override
public void onSurfaceTextureAvailable(SurfaceTexture surface, int width, int height) {
Log.i(TAG, "InicializoSurface. Width: " + width + " HEIGHT:" + height);
Log.i(TAG, "InicializoSurface. Width: " + mVideoView.getMeasuredWidth() + " HEIGHT:" + mVideoView.getMeasuredHeight());
Log.i(TAG, "View transform. Width: " + mVideoView.getWidth() + " HEIGHT:" + mVideoView.getHeight());
mMediaSurface = new Surface(mVideoView.getSurfaceTexture());
initializeMediaPlayer();
}
@Override
public void onSurfaceTextureSizeChanged(SurfaceTexture surface, int width, int height) {
}
@Override
public boolean onSurfaceTextureDestroyed(SurfaceTexture surface) {
if (mMediaPlayer != null) {
// Make sure we stop video and release resources when activity is destroyed.
mMediaPlayer.stop();
mMediaPlayer.release();
mMediaPlayer = null;
}
return false;
}
@Override
public void onSurfaceTextureUpdated(SurfaceTexture surface) {
}
//////////
private void initializeMediaPlayer(){
mMediaPlayer = new CustomMediaPlayer();
Uri uri = Uri.parse(mCameraDataAdapter.getList().get(0).getPath());
try {
mMediaPlayer.setDataSource(mActivity, uri);
mMediaPlayer.setSurface(mMediaSurface);
mMediaPlayer.prepareAsync();
mMediaPlayer.setOnPreparedListener(mMediaPlayer);
mMediaPlayer.setOnCompletionListener(mMediaPlayer);
} catch (IOException e) {
e.printStackTrace();
}
}
///////////
mVideoView.setVisibility(View.VISIBLE);
// mVideoView.setTranslationX(-200);
// mVideoView.setTranslationY(-200);
Log.i(TAG, "X: " + mVideoView.getX() + "Y: " + mVideoView.getY());
if (mVideoView.isAvailable()) {
onSurfaceTextureAvailable(mVideoView.getSurfaceTexture(), mVideoView.getWidth(), mVideoView.getHeight());
}
if (mMediaPlayer == null) {
initializeMediaPlayer();
}
// mMediaPlayer.mVideoHolder = mVideoView.getHolder();
// mMediaPlayer.setDisplay(mMediaPlayer.mVideoHolder);
if (mMediaPrepared) {
Log.i(TAG,"Comienzo Video");
mMediaPlayer.start();
}
最後，這裏是我onMeasure/OnLayout從我CustomView
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
int width;
int height;
int wantedWidth = 0;
int wantedHeight = 0;
if(mWidth == 0 && mHeight == 0){
mWidth = MeasureSpec.getSize(widthMeasureSpec);
mHeight =MeasureSpec.getSize(heightMeasureSpec);
}
width = mWidth;
height = mHeight;
if (mOrientation == 0 || mOrientation == 180) {
wantedWidth = width - (int)(mMargin * 2);
mVideo.measure(MeasureSpec.makeMeasureSpec(wantedWidth, MeasureSpec.EXACTLY), MeasureSpec.makeMeasureSpec((int) (wantedWidth * mVideoAspectRatio), MeasureSpec.EXACTLY));
wantedHeight = (mViewTop.getLayoutParams().height) * 2 + (int) (wantedWidth * mAspectRatio);
} else {
Log.e(TAG, "Real Width = " + width + " real Height = " + height);
wantedHeight = width - 2 * mViewTop.getLayoutParams().height - (int)(mMargin * 2);
mVideo.measure(MeasureSpec.makeMeasureSpec(wantedHeight, MeasureSpec.EXACTLY),MeasureSpec.makeMeasureSpec((int) (wantedHeight * mAspectRatio), MeasureSpec.EXACTLY));
//
wantedWidth =(int) (wantedHeight * mAspectRatio) ;
wantedHeight = width - (int)(mMargin * 2);
}
Log.e(TAG, "onMeasure: " + wantedWidth + "x" + wantedHeight);
setMeasuredDimension(MeasureSpec.makeMeasureSpec(wantedWidth, MeasureSpec.EXACTLY), MeasureSpec.makeMeasureSpec(wantedHeight, MeasureSpec.EXACTLY));
}
@Override
protected void onLayout(boolean changed, int l, int t, int r, int b) {
int w = getMeasuredWidth();
int h = getMeasuredHeight();
int viewHeight = mViewBottom.getMeasuredHeight();
int imageViewHeight = mImage.getMeasuredHeight();
int wantedHeight = 0;
// w = w - (int) (2 * mMargin);
if (mOrientation == 0 || mOrientation == 180) {
mVideo.layout(0,wantedHeight,w,wantedHeight + imageViewHeight);
}else{
mVideo.layout(viewHeight,0,r-viewHeight - (int) mMargin,w);
}
}
我已經工作在試圖解決這個最後的日子，但我沒有得到任何方法來解決它，我一直在尋找其他職位Android MediaRecorder making rotated video，我看到它不可能旋轉textureView，但我不能相信我可以旋轉一個形象如此輕鬆，在這期間必須爭取將90度視頻旋轉..
希望有人能夠找到解決方案！祝你有美好的一天！
使用'TextureView＃setTransform（矩陣變換）' – pskink
@pskink我已經嘗試過使用Matrix和SetTransform，它什麼也不做。在測量所有內容之前，當我調用Surface或我選擇照片時，我嘗試了它。視頻不會改變，它保持與以前完全一樣：S –
'setTransform'正常工作，我使用過很多次，基本上你的'Matrix'是以錯誤的方式計算的 – pskink
