我想将数据库中存储的图像添加到ViewFlipper的图像视图中。但是当我添加这些图像时,我遇到了一些错误。请帮助我解决该问题,或者让我知道是否有其他解决方案。这是我的代码:
MainActivity.java
public class MainActivity extends AppCompatActivity {
DatabaseHelper myDb;
EditText editImagename;
Button btnAddData;
Button btnview;
ImageView imgview;
ViewFlipper viewflips;
private static int RESULT_LOAD_IMAGE = 1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_main);
editImagename = findViewById(R.id.image_name);
btnAddData = findViewById(R.id.addbtn);
btnview = findViewById(R.id.getbtn);
imgview = new ImageView(this);
viewflips = findViewById(R.id.viewflip);
viewAll();
TextView txt = findViewById(R.id.text);
txt.setSelected(true);
Button buttonLoadImage = findViewById(R.id.btn1);
buttonLoadImage.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
Intent i = new Intent(Intent.ACTION_PICK,Uri.parse("content://media/internal/images/media"));
startActivityForResult(i, RESULT_LOAD_IMAGE);
}
});
myDb = new DatabaseHelper(this);
}
