android彈出菜單

Question

我已按照本教程在透明背景上創建搜索欄。 按下按鈕時如何使其在屏幕上彈出？

Answer 1

您可以在應用程序中添加一個按鈕，然后使用該按鈕將搜索欄的可見性從View.GONE為View.VISIBLE 。 像這樣：

final TransparentPanel transparentPanel = ... //however you initialize
transparentPanel.setVisibility(View.GONE); //make it invisible to start
button.setOnClickListener(new View.OnClickListener(){
    //Make the panel visible whenever someone clicks on your new button
    transparentPanel.setVisibility(View.VISIBLE);
});

//add the button to whatever ViewGroup transparentPanel lives in
