Android Studio - 如何在 Java 中以编程方式为 TextInputLayout 设置文本？

Question

To set text for views like EditText, I simply need to use setText("text") function, but I can't do that to TextInputLayout. How do I set text for TextInputLayout?

Answer 1

Just have to set the the to the TexInputEditText .

   <com.google.android.material.textfield.TextInputLayout
        android:id="@+id/textInputLayout"
        ..>
        <com.google.android.material.textfield.TextInputEditText/>
    </com.google.android.material.textfield.TextInputLayout>

Something like:

textInputLayout.getEditText().setText("text");

Answer 2

To set text in TextInputLayout you'd need to create an EditText within it.
Something like:

TextInputLayout parent = (TextInputLayout) findViewById(R.id.parent);
        EditText editText = new EditText;
        editText.setText("the text");
        editText.setLayoutParams(new TextInputLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT));
        parent.addView(editText);
        }
