Android 单击ImageView时，图像不会全屏显示

单击

imageView

时，我想显示我的

位图

图像的全屏（从gallery或captured image中选择）

 imageView .setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
              if(zoomOut) {
              Toast.makeText(getApplicationContext(), "NORMAL SIZE!", Toast.LENGTH_LONG).show();
                    imageView.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT));
                    imageView.setAdjustViewBounds(true);
                    zoomOut =false;
                }else{
              Toast.makeText(getApplicationContext(), "FULLSCREEN!", Toast.LENGTH_LONG).show();
                    imageView.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT));
                    imageView.setScaleType(ImageView.ScaleType.FIT_XY);
                    zoomOut = true;
                }
            }                   
    });

这是我的xml（活动B）

活动B

点击后

再次单击以缩小

使用以下命令编辑代码

TextView mTextViewClaims = (TextView) findViewById(R.id.textViewClaims);
TextView mTextViewClaimsType = (TextView) findViewById(R.id.textViewClaimsType);
TextView mTextViewAmount = (TextView) findViewById(R.id.textViewAmount);
TextView mTextView12 = (TextView) findViewById(R.id.textView12);

EditText mEditTextAmount = (EditText) findViewById(R.id.editTextAmount);
EditText mTextDescription = (EditText) findViewById(R.id.textDescription);

Button mButtonAdd = (Button) findViewById(R.id.buttonAdd);
Button mButtonSave = (Button) findViewById(R.id.buttonSave);

imageView .setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
          if(zoomOut) {
          Toast.makeText(getApplicationContext(), "NORMAL SIZE!", Toast.LENGTH_LONG).show();

                float scale = getContext().getResources().getDisplayMetrics().density;
                imageView.setLayoutParams(new LinearLayout.LayoutParams((int)(350 * scale + 0.5f) , (int)(300 * scale + 0.5f)));
                imageView.setAdjustViewBounds(true);

                mTextViewClaims.setVisibility(View.VISIBLE);
                mTextViewClaimsType.setVisibility(View.VISIBLE);

好的，我明白了，首先你必须使用相对论！，让我举个例子（现在尝试相对布局）。@Elenasys谢谢。我希望它只在放大时显示图像。@Elenasys我必须更改布局中的所有内容？有人有解决方案吗？@Tony是的，我用解决方案更新了我的答案谢谢你的回答：）图像现在变大了，但仍然不能全屏显示。我仍然可以看到活动B中的文本。这意味着您只想显示图像，而不想显示其他内容。对吗？没错。当它再次点击时，它将缩小（与活动B完全相同）Tony，如果你使元素不可见会怎么样？@Tony answer用代码更新，让我知道它是否有效。。！！
