There is a piece of code, the layout timetablel.xml exists, the class includes "activity", the activity is also specified in AndroidManifest . There are no errors when launching the application, when switching to the problematic activity too. Only instead of elements from the file, there is a white sheet enter image description here

  protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.timetablel); editText=(EditText)findViewById(R.id.editText); editText2=(EditText)findViewById(R.id.editText2); editText3=(EditText)findViewById(R.id.editText3); editText4=(EditText)findViewById(R.id.editText4); editText5=(EditText)findViewById(R.id.editText5); editText6=(EditText)findViewById(R.id.editText6); btnReady=(Button)findViewById(R.id.btnReady); mSettings = getSharedPreferences(APP_SETTINGS, Context.MODE_PRIVATE); btnReady.setOnClickListener(this); }

layout:

  • Give the markup of the problem activation. - Yuriy SPb ♦

Most likely the problem is in weight and height of the markup elements.

When using weight, height must be equated to 0dip , i.e. like that:

 android:layout_weight="SOME_VALUE" android:layout_height="0dip"

Also, the weight of the first TextView is not specified at all. And the amount of weight does not match, as I understand it, with the given in the root element.

  • Thank you, now I will try to correct. But still I didn’t quite understand, I have another layout, where such code is: - Vladimir51
  • android: layout_width = "match_parent" android: layout_height = "wrap_content" android: text = "Hello, Anatoly!" android: id = "@ + id / textView3" android: layout_weight = "0.13" android: textColor = "@ color / textv" android: textStyle = "bold" android: textSize = "40dp" /> - Vladimir51
  • But it works! - Vladimir51
