Question

在虚拟手机菜单中显示。但它没有显示在我的个人手机中。我在这里保留了mainactivity.java，main.xml，androidmainfest.xml个文件。请回答任何问题...... < / p>

//mainactivity.java
public class MainActivity extends Activity{
    String username,password;     ResultSet rs =null;
    boolean temcfag=false;
    static boolean temqfag=true;
    public static String tag="Lifecycle activity";
    EditText user,pass;
    AlertDialog.Builder dialog;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        dialog=new AlertDialog.Builder(this);
        dialog.setNeutralButton("OK", null);


        user=(EditText)findViewById(R.id.editText1);
        pass=(EditText)findViewById(R.id.editText2);
           final Button click=(Button)findViewById(R.id.button2);       
           click.setOnClickListener(new View.OnClickListener() {                                            
                        public void onClick(View v) 
                          {             
Intent launchactivity= new Intent(MainActivity.this,com.example.desisquarea.LoginActivity.class);                               
startActivity(launchactivity);                          
                            }
                             });   

    }
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }
}

Answer 1

      lp.gravity = Gravity.TOP | Gravity.RIGHT;
     myDialog.getWindow().setAttributes(lp);
     dialog.show();
