我知道如何从图库中pickUp
Image
。但是相同的代码在我的其他应用程序中工作但在我的新应用程序中不起作用。
public class RegisterActivity extends AppCompatActivity{
Button upload_proof_button;
Bitmap bitmaps;
private static final int PICK_IMAGE = 100;
ImageView filename;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_register);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
filename = (ImageView) findViewById(R.id.filename_textveiw);
upload_proof_button = (Button)findViewById(R.id.upload_proof_button);
upload_proof_button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent gallery = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI);
startActivityForResult(gallery, PICK_IMAGE);
}
});
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK && requestCode == PICK_IMAGE) {
Uri imageUri = data.getData();
try {
bitmaps = MediaStore.Images.Media.getBitmap(this.getContentResolver(), imageUri);
if(bitmaps == null){
filename.setImageBitmap(bitmaps);
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
我在manifest.xml
文件中写了权限。
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

clean
项目。Invalidate and caches
。任何帮助都要得到赞赏..
答案 0 :(得分:0)
您检查位图是否为null
以将其设置为ImageView。改为:
if (bitmaps != null) {
filename.setImageBitmap(bitmaps);
} else {
filename.setImageResource(R.drawable.default_image);
}
