如何從屏幕底部向上滑出壹個view-Android開發問答

從屏幕底部向上滑出壹個view的方式，主要是使用TranslateAnimation，這個類，可以綁定壹個控件，在y軸方向，滑出壹段高度，如下代碼：

import?android.app.Activity;?

import?android.os.Bundle;?

import?android.view.View;?

import?android.view.animation.Animation;?

import?android.view.animation.AnimationUtils;?

import?android.view.animation.TranslateAnimation;?

import?android.widget.Button;?

import?android.widget.TextView;?

public?class?AndroidAnimationActivity?extends?Activity?{?

private?Animation?myAnimation_Translate;?

@Override?

public?void?onCreate(Bundle?savedInstanceState)?{?

super.onCreate(savedInstanceState);?

setContentView(R.layout.main);?

final?TextView?tv?=?(TextView)?findViewById(R.id.tv);?

Button?btn?=?(Button)?findViewById(R.id.btn);?

btn.setOnClickListener(new?View.OnClickListener()?{?

@Override?

public?void?onClick(View?v)?{?

tv.setVisibility(View.VISIBLE);?

myAnimation_Translate?=?new?TranslateAnimation(?

Animation.RELATIVE_TO_PARENT,?-1,?

Animation.RELATIVE_TO_PARENT,?0,?

Animation.RELATIVE_TO_PARENT,?0,?

Animation.RELATIVE_TO_PARENT,?0);?

myAnimation_Translate.setDuration(1000);?

myAnimation_Translate.setInterpolator(AnimationUtils?

.loadInterpolator(AndroidAnimationActivity.this,?

android.R.anim.accelerate_decelerate_interpolator));?

tv.startAnimation(myAnimation_Translate);?

}?

});?

}?

}
