我编写了一个程序来浏览图库,并使用AndroidStudio在ImageView中显示所选图像。我有Select Image From Gallery And Display It On ImageView, Issue On Nexus 5
的示例代码它正在运行良好的股票Android运行智能手机像LG L70集。但在Xiomi 4A的imageview上看不到任何图像。
对于实验,我在Eclipse编辑器中编写了相同的代码。 Eclipse开发的代码运行良好,LG L70和Xiomi 4A。
因此,很明显代码不是问题。问题必须来自IDE。你能帮我解决这个问题吗?我应该在哪里修改代码,以便它可以在AndroidStudio开发的Xiomi上运行。
代码
package com.example.nasif.xiomi_imageview2;
import android.content.Intent;
import android.net.Uri;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.Toast;
import static android.widget.Toast.LENGTH_LONG;
public class MainActivity extends AppCompatActivity
{
private ImageView imgProfile;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
imgProfile = (ImageView)findViewById(R.id.imgProfileIV);
final Button button = (Button) findViewById(R.id.button1);
button.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
// Perform action on click
//new MyAsyncTask(this).execute("ppppp");
Log.d("MyTag", "1");
ImageProfile();
}
});
}
public void ImageProfile()
{
Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
photoPickerIntent.setType("image/*");
startActivityForResult(photoPickerIntent, 100);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent)
{
super.onActivityResult(requestCode, resultCode, imageReturnedIntent);
switch(requestCode)
{
case 100:
if(resultCode == RESULT_OK)
{
Uri selectedImage = imageReturnedIntent.getData();
imgProfile.setImageURI(selectedImage);
Log.d("MyTag", "@: " + selectedImage);
Toast.makeText(MainActivity.this, "@: " + selectedImage, LENGTH_LONG).show();
}
}
}
}
