Android 子视图高度与 ListView 项中的父视图不匹配 [英] Android child view height not match parent in ListView item
本文介绍了Android 子视图高度与 ListView 项中的父视图不匹配的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
如上所述，我的列表项是一个FrameLayout，里面有两个视图.
As described, my List item is a FrameLayout, there are two views inside.
ColorView 是我为在整个视图中显示颜色而制作的自定义视图.
ColorView is a custom view I made for show color in whole view.
(FrameLayout 的高度为 "wrap_content")
(FrameLayout's height is "wrap_content")
它似乎在我的 ICS 设备上运行良好，但不适用于我的 Android 2.2 模拟器和 Android 1.6 G1.
It seems work well on my ICS device, but doesn't work on my Android 2.2 emulator and Android 1.6 G1.

是否有任何变通方法或其他方法可以解决此问题?
does it have any workaround or other way to solve this?

ColorView 的代码
package org.mariotaku.twidere.view;
import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.util.AttributeSet;
import android.view.View;
public class ColorView extends View {
private int mColor = Color.TRANSPARENT;
public ColorView(Context context) {
this(context, null);
}
public ColorView(Context context, AttributeSet attrs) {
this(context, attrs, 0);
}
public ColorView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
public void setColor(int color) {
mColor = color;
invalidate();
}
@Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
canvas.drawColor(mColor);
}
}

好难过，没人知道怎么处理.
so sad, nobody knows how to deal with this.
但最后我使用了一种解决方法来解决这个问题.
but finally I used a workaround to solve this problem.

}
@Override
public void onSizeChanged(int w, int h, int oldw, int oldh) {
mRectBackground.set(0, 0, w, h);
mRectLeft.set(0, 0, (int)(4 * mDensity), h);
mRectRight.set(w - (int)(4 * mDensity), 0, w, h);
super.onSizeChanged(w, h, oldw, oldh);
}
}
它对我来说效果很好.
