这个范例是选取SD卡中的照片再显示在Imageview中 放到手机执行的话第一次选取很正常 但是直接再按Picture选取一次的话他就会直接中止程式 我想请问如果我想要把它改成可以再更改一次图片的话要怎麽做呢? 程式码好像不算长我就直接贴了 或是我有把这个范例上传 网址http://www.badongo.com/file/25710607 麻烦大家指点了 public class EX07_06 extends Activity { private Button myButton01; private ImageView myImageView01; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); myImageView01 = (ImageView) findViewById(R.id.myImageView01); myButton01 = (Button) findViewById(R.id.myButton01); myButton01.setOnClickListener(new Button.OnClickListener() { @Override public void onClick(View arg0) { Intent intent = new Intent(); /* 开启Pictures画面Type设定为image */ intent.setType("image/*"); /* 使用Intent.ACTION_GET_CONTENT这个Action */ intent.setAction(Intent.ACTION_GET_CONTENT); /* 取得相片後返回本画面 */ startActivityForResult(intent, 1); } }); } @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { if (resultCode == RESULT_OK) { Uri uri = data.getData(); ContentResolver cr = this.getContentResolver(); try { Bitmap bitmap = BitmapFactory.decodeStream(cr .openInputStream(uri)); /* 将Bitmap设定到ImageView */ myImageView01.setImageBitmap(bitmap); } catch (FileNotFoundException e) { e.printStackTrace(); } } super.onActivityResult(requestCode, resultCode, data); } } --
