Textview Height Wrap_content But Not More Than 30 Percent Of Parent

My screen is divided into two layouts. Left side(clients_list_layout) is OK, but I have one problem with right side(detail_layout). It consists of two TextViews. I want first TV to

Solution 1:

I have similar issue and finally end up with custom layout, based on LinearLayout. I override onMeasure method for this layout to set it's child views width either to wrap content or width proportional to weight value:

package com.snaprix.androidfrequentlyused.views;

import android.content.Context;
import android.util.AttributeSet;
import android.view.View;
import android.widget.LinearLayout;

/**

 */publicclassEvenLayoutextendsLinearLayout {
    privatestaticbooleanDEBUG=false;
    privatestaticfinalStringTAG="EvenLayout";

    publicstaticvoidsetDebug(boolean debug){
        DEBUG = debug;
    }

    publicEvenLayout(Context context) {
        super(context);
    }

    publicEvenLayout(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    publicEvenLayout(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @OverrideprotectedvoidonMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);

        finalintwidthMode= MeasureSpec.getMode(widthMeasureSpec);
        finalintheightMode= MeasureSpec.getMode(heightMeasureSpec);

        finalintwidth= MeasureSpec.getSize(widthMeasureSpec);
        finalintheight= MeasureSpec.getSize(heightMeasureSpec);

        finalintcount= getChildCount();
        floattotalWeight=0;
        for (inti=0; i < count; ++i) {
            finalViewchild= getChildAt(i);

            if (child.getVisibility() == GONE) {
                continue;
            }

            finalLayoutParamslp= (LayoutParams)
                    child.getLayoutParams();

            totalWeight += lp.weight;

            measureChildWithMargins(child, widthMeasureSpec, 0, heightMeasureSpec, 0);
        }

        intaccWidth=0;
        for (inti=0; i < count; ++i) {
            finalViewchild= getChildAt(i);

            if (child.getVisibility() == GONE) {
                continue;
            }

            if (i < count - 1) {
                finalLayoutParamslp= (LayoutParams)
                        child.getLayoutParams();
                if (lp.weight > 0) {
                    intmaxChildWidth= (int) (lp.weight / totalWeight * width);
                    if (maxChildWidth < child.getMeasuredWidth()) {
                        child.measure(
                                MeasureSpec.makeMeasureSpec(maxChildWidth, MeasureSpec.EXACTLY),
                                heightMeasureSpec);
                    }
                }
                accWidth += child.getMeasuredWidth();
            } else {
                intremainingWidth= width - accWidth;
                child.measure(
                        MeasureSpec.makeMeasureSpec(remainingWidth, MeasureSpec.EXACTLY),
                        heightMeasureSpec);
            }
        }
    }
}

Sample activity with this layout:

<FrameLayoutxmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent"><com.snaprix.androidfrequentlyused.views.EvenLayoutandroid:layout_width="match_parent"android:layout_height="wrap_content"android:orientation="horizontal"><TextViewandroid:text="Framer Studio 1.6 with Revamped Sketch Support"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_weight="30"android:singleLine="true"/><TextViewandroid:text="In close collaboration with the Bohemian Coding team, we’re happy to announce much improved Sketch support in Framer Studio"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_weight="70"android:singleLine="true"/></com.snaprix.androidfrequentlyused.views.EvenLayout></FrameLayout>

Solution 2:

try this

<LinearLayoutandroid:id="@+id/detail_layout"android:layout_width="0dp"android:layout_height="match_parent"android:layout_weight="50"android:orientation="vertical"android:weightSum="100" ><TextViewandroid:id="@+id/client_comments"android:layout_width="match_parent"android:layout_height="fill_parent"android:layout_weight="70"android:padding="5dp"android:scrollbarAlwaysDrawVerticalTrack="true"android:scrollbars="vertical"android:text=""android:textSize="20sp"tools:ignore="NestedWeights" /><TextViewandroid:id="@+id/client_debt"android:layout_width="match_parent"android:layout_height="fill_parent"android:layout_weight="30"android:padding="2dp"android:textSize="20sp"android:text="" /></LinearLayout>
