这是对上篇”android 图片拍照,相册选图,剪切并显示”的文章之后的 改进
上一篇文章虽然能解决图片的拍照剪切以及显示,但是发现他有一个缺点, 如果该程序单独运行,貌似没有任何问题, 但是把它整合到项目中后,发现有时在小米手机或者三星手机上面仍旧会失败, 原因可能是 拍照后导致内存不足,从而拍照后返回的时候,没有返回数据,导致图片显示失败,当然这是一定的概率事件.
针对这一情况做如下改变,代码如下:
package com.kuiboo.xiaoyao.Activity;import android.app.Activity;
import android.content.Intent;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.net.Uri;

import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.util.Random;public class EditMineActivity extends Activity {
private static final String TAG = "MainActivity";
private static final int TAKE_SMALL_PICTURE = 2;
private static final int CROP_BIG_PICTURE = 3;
private static final int CROP_SMALL_PICTURE = 4;
private static final int CHOOSE_SMALL_PICTURE = 6;
private static final String IMAGE_FILE_LOCATION = "file:///sdcard/temp.jpg";
private Uri imageUri;//存储图片的uri地址
CircleImageView iv;//自定义圆形图片,或者使用第三方库,或者基本ImageView都可以
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_mine_edit);
Log.e("执行了几次","aaa");
iv= (CircleImageView) findViewById(R.id.photoView);
iv.setBorderWidth(5);
imageUri = Uri.parse(IMAGE_FILE_LOCATION);
iv.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
new ActionSheetDialog(EditMineActivity.this).Builder()
.addSheetItem("拍照", ActionSheetDialog.SheetItemColor.BULE, new ActionSheetDialog.OnSheetItemClickListener() {
@Override
public void onClick(int witch) {
openCamera();
}
}).addSheetItem("打开相册", ActionSheetDialog.SheetItemColor.BULE, new ActionSheetDialog.OnSheetItemClickListener() {
@Override
public void onClick(int witch) {
openPic();
}
}).show();
}
});
} //获取相册图片
private void openPic() {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT, null);
intent.setType("image/*");
intent.putExtra("crop", "true");
intent.putExtra("aspectX", 2);
intent.putExtra("aspectY", 1);
intent.putExtra("outputX", 200);

startActivityForResult(intent, CHOOSE_SMALL_PICTURE);
} //获取拍照小图片
private void openCamera() {
if(imageUri == null) {
Log.e(TAG, "图片uri不能为空!");
}
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
startActivityForResult(intent, TAKE_SMALL_PICTURE);
}
//剪切
private void cropImageUri(Uri uri, int outputX, int outputY, int requestCode){
Intent intent = new Intent("com.android.camera.action.CROP");
intent.setDataAndType(uri, "image/*");
intent.putExtra("crop", "true");
intent.putExtra("aspectX", 2);
intent.putExtra("aspectY", 1);
intent.putExtra("outputX", outputX);
intent.putExtra("outputY", outputY);
intent.putExtra("scale", true);
intent.putExtra(MediaStore.EXTRA_OUTPUT, uri);
intent.putExtra("return-data", false);
intent.putExtra("outputFormat", Bitmap.CompressFormat.JPEG.toString());
intent.putExtra("noFaceDetection", true); // 没有人脸识别
startActivityForResult(intent, requestCode);
} private Bitmap decodeUriAsBitmap(Uri uri){
Bitmap bitmap = null;
try {
bitmap = BitmapFactory.decodeStream(getContentResolver().openInputStream(uri));
} catch (FileNotFoundException e) {
e.printStackTrace();
return null;
}
return bitmap;
} @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(resultCode != Activity.RESULT_OK){
Log.e(TAG, "requestCode = " + requestCode);
Log.e(TAG, "resultCode = " + resultCode);
Log.e(TAG, "data = " + data);
return;
}else{
switch (requestCode) {
// case CROP_BIG_PICTURE://剪切大图
// if(imageUri != null){
// Bitmap bitmap = decodeUriAsBitmap(imageUri);
// iv.setImageBitmap(bitmap);
// }
// break;
case TAKE_SMALL_PICTURE://拍照
cropImageUri(imageUri, 260, 200, CROP_SMALL_PICTURE);
break;
case CROP_SMALL_PICTURE://剪切小图
if(imageUri != null){
Bitmap bitmap = decodeUriAsBitmap(imageUri);
iv.setImageBitmap(bitmap);
}else{
Log.e(TAG, "CROP_SMALL_PICTURE: data = " + data);
}
break; case CHOOSE_SMALL_PICTURE://相册选择
if(data != null){
Bitmap bitmap = data.getParcelableExtra("data");
iv.setImageBitmap(bitmap);
}else{
Log.e(TAG, "CHOOSE_SMALL_PICTURE: data = " + data);
}
break;
}
}
}
}
效果图就不上了 ,和上一篇文章效果图一样.
