這個範例是選取SD卡中的照片再顯示在Imageview中 放到手機執行的話第一次選取很正常 但是直接再按Picture選取一次的話他就會直接中止程式 我想請問如果我想要把它改成可以再更改一次圖片的話要怎麼做呢? 程式碼好像不算長我就直接貼了 或是我有把這個範例上傳 網址http://www.badongo.com/file/25710607 麻煩大家指點了 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(); /* 開啟Pictures畫面Type設定為image */ intent.setType("image/*"); /* 使用Intent.ACTION_GET_CONTENT這個Action */ intent.setAction(Intent.ACTION_GET_CONTENT); /* 取得相片後返回本畫面 */ 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)); /* 將Bitmap設定到ImageView */ myImageView01.setImageBitmap(bitmap); } catch (FileNotFoundException e) { e.printStackTrace(); } } super.onActivityResult(requestCode, resultCode, data); } } --
