Android EditText 3.5 行

Question

I have to show max 3.5 lines in my EditText if lines are more then 3. I tried lots of property but still not able to implement that.

If a set android:layout_height="wrap_content" it will show N number of lines.

Do we have any property combination or I'll have to do it manually.

Say I fixed some height to android:layout_height="36dp" and if line count is >= 4 again I have to set android:layout_height="48dp" in this way i'll achieve what I am looking for.

编辑

public void onTextChanged(CharSequence s, int start, int before, int count){                    
    FrameLayout.LayoutParams lp  = (FrameLayout.LayoutParams) txtMessage.getLayoutParams();
    if(txtMessage.getLineCount() > 3){
        if(lp.height != 0) {
            txtMessage.getLayoutParams().height = 0;
        }
    }else if(lp.height != ViewGroup.LayoutParams.WRAP_CONTENT){
        txtMessage.getLayoutParams().height = ViewGroup.LayoutParams.WRAP_CONTENT;
    }
}

为我显示至少 3 行 :)

Answer 1

您可以使用 android:maxLines="3" 强制 EditText 显示不超过 3 行。

但对于 3.5，您只能通过手动设置 EditText 高度来实现。

Answer 2

对 Edittext 使用以下代码

使用android:inputType="textMultiLine"和android:lines="3"

<EditText
    android:id="@+id/edittext"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:inputType="textMultiLine"
    android:lines="3" />
