I am trying to do a app with multiple EditText
and is wondering if there is any easy way to do that.
For instance to add matrix of EditText
from your java code to your activity_main.xml
or maby do a for loop which adds them at your specified location.
EditText[][] edittext = new EditText[10][10];
gridView = (GridView) findViewById(R.id.gridview);
for (int i=0;i<9;i++){
for (int j=0;j<9;j++){
gridView.addView(edittext[i][j], column X, row Y);
}
}
There is no easier way to make a "form". Each EditText is a different xml component with different id, with its own attributes.
What you can do is an adapter with listview/recyclerview with EditText the holder.
Here is a working example..
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
LinearLayout root = (LinearLayout) findViewById(R.id.master);
EditText t[][] = new EditText[10][10];
LinearLayout.LayoutParams dim = new LinearLayout.LayoutParams(LinearLayout.LayoutParams
.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
for (int i=0;i<9;i++){
for (int j=0;j<9;j++){
t[i][j]=new EditText(this);
t[i][j].setLayoutParams(dim);
t[i][j].setHint("Hello World , EditText[" + i + "]" + "[" + j + "]");
root.addView(t[i][j]);
}
}
}
You can do smth like that:
ArrayList<EditText> editTexts = new ArrayList<>();
LinearLayout ll = (LinearLayout) findViewById(R.id.container);
EditText oneOfEditText;
for (int i = 0; i < 100; i++){
oneOfEditText = new EditText(this);
oneOfEditText.setLayoutParams(new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT
));
oneOfEditText.setHint("MyHint");
oneOfEditText.setId(i);
ll.addView(oneOfEditText);
editTexts.add(oneOfEditText);
}
And then you can access these EditTexts like that:
for (EditText editText : editTexts){
Log.d("myLog", editText.getText().toString());
}
But the best practice for such things is to create them statically in xml, and then you can access them either via static ids, or like that:
for (int i =0; i < ll.getChildCount(); i++){
editTexts.add((EditText) ll.getChildAt(i));
}
I think the proper way implement each item is to use an adapter. In your case, you can use SimpleAdapter
or create a custom adapter that extends BaseAdapter
and set it using setAdapter(ListAdapter)
.
You can check the documentation for GridView here: http://developer.android.com/guide/topics/ui/layout/gridview.html
