上下居中怎么弄，android頂部居中,如何將drawableLeft對齊到頂部,而不是在android TextView中居中？

見

my answer here。

您可以通過創建包裝您的Drawable的自定義Drawable，然后通過覆蓋方法onDraw(Canvas)來操作您的自定義Drawable的繪圖來將一個復合Drawable(或底部)對齊。

以下示例是最簡單的示例。這將圖像與頂部對齊，但您也可以通過在onDraw(Canvas)方法中實現所需的邏輯使其與TextView的底部，左側或右側對齊。您可能還需要在onDraw(Canvas)中構建邊距，使您的設計實現像素完美。

樣品用量：

上下居中怎么弄。GravityCompoundDrawable gravityDrawable = new GravityCompoundDrawable(innerDrawable);

// NOTE: next 2 lines are important!

innerDrawable.setBounds(0, 0, innerDrawable.getIntrinsicWidth(), innerDrawable.getIntrinsicHeight());

gravityDrawable.setBounds(0, 0, innerDrawable.getIntrinsicWidth(), innerDrawable.getIntrinsicHeight());

mTextView.setCompoundDrawables(gravityDrawable, null, null, null);

示例代碼：

水平居中對齊，public class GravityCompoundDrawable extends Drawable {

// inner Drawable

private final Drawable mDrawable;

public GravityCompoundDrawable(Drawable drawable) {

mDrawable = drawable;

}

安卓垂直居中。@Override

public int getIntrinsicWidth() {

return mDrawable.getIntrinsicWidth();

}

@Override

public int getIntrinsicHeight() {

word水平居中怎么設置。return mDrawable.getIntrinsicHeight();

}

@Override

public void draw(Canvas canvas) {

int halfCanvas= canvas.getHeight() / 2;

int halfDrawable = mDrawable.getIntrinsicHeight() / 2;

表格文字水平居中怎么設置、// align to top

canvas.save();

canvas.translate(0, -halfCanvas + halfDrawable);

mDrawable.draw(canvas);

canvas.restore();

}
